BMI formula calculator

The Body Mass Index (BMI) Calculator can be used to calculate BMI value and corresponding weight status while taking age into consideration. Use the “Metric Units” tab for the International System of Units or the “Other Units” tab to convert units into either US or metric units. Note that the calculator also computes the Ponderal Index in addition to BMI, both of which are discussed below in detail.

BMI introduction

BMI is a measurement of a person’s leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. It is widely used as a general indicator of whether a person has a healthy body weight for their height. Specifically, the value obtained from the calculation of BMI is used to categorize whether a person is underweight, normal weight, overweight, or obese depending on what range the value falls between. These ranges of BMI vary based on factors such as region and age, and are sometimes further divided into subcategories such as severely underweight or very severely obese. Being overweight or underweight can have significant health effects, so while BMI is an imperfect measure of healthy body weight, it is a useful indicator of whether any additional testing or action is required. Refer to the table below to see the different categories based on BMI that is used by the calculator.

BMI table for adults

This is the World Health Organization’s (WHO) recommended body weight based on BMI values for adults. It is used for both men and women, age 18 or older.

CategoryBMI range – kg/m2
Severe Thinness< 16
Moderate Thinness16 – 17
Mild Thinness17 – 18.5
Normal18.5 – 25
Overweight25 – 30
Obese Class I30 – 35
Obese Class II35 – 40
Obese Class III> 40

BMI table for children and teens, age 2-20

The Centers for Disease Control and Prevention (CDC) recommends BMI categorization for children and teens between age 2 and 20.

CategoryPercentile Range
Underweight<5%
Healthy weight5% – 85%
At risk of overweight85% – 95%
Overweight>95%

Risks associated with being overweight

Being overweight increases the risk of a number of serious diseases and health conditions. Below is a list of said risks, according to the Centers for Disease Control and Prevention (CDC):

  • High blood pressure
  • Higher levels of LDL cholesterol, which is widely considered “bad cholesterol,” lower levels of HDL cholesterol, considered to be good cholesterol in moderation, and high levels of triglycerides
  • Type II diabetes
  • Coronary heart disease
  • Stroke
  • Gallbladder disease
  • Osteoarthritis, a type of joint disease caused by breakdown of joint cartilage
  • Sleep apnea and breathing problems
  • Certain cancers (endometrial, breast, colon, kidney, gallbladder, liver)
  • Low quality of life
  • Mental illnesses such as clinical depression, anxiety, and others
  • Body pains and difficulty with certain physical functions
  • Generally, an increased risk of mortality compared to those with a healthy BMI

As can be seen from the list above, there are numerous negative, in some cases fatal, outcomes that may result from being overweight. Generally, a person should try to maintain a BMI below 25 kg/m2, but ideally should consult their doctor to determine whether or not they need to make any changes to their lifestyle in order to be healthier.

Risks associated with being underweight

Being underweight has its own associated risks, listed below:

  • Malnutrition, vitamin deficiencies, anemia (lowered ability to carry blood vessels)
  • Osteoporosis, a disease that causes bone weakness, increasing the risk of breaking a bone
  • A decrease in immune function
  • Growth and development issues, particularly in children and teenagers
  • Possible reproductive issues for women due to hormonal imbalances that can disrupt the menstrual cycle. Underweight women also have a higher chance of miscarriage in the first trimester
  • Potential complications as a result of surgery
  • Generally, an increased risk of mortality compared to those with a healthy BMI

In some cases, being underweight can be a sign of some underlying condition or disease such as anorexia nervosa, which has its own risks. Consult your doctor if you think you or someone you know is underweight, particularly if the reason for being underweight does not seem obvious.

Limitations of BMI

Although BMI is a widely used and useful indicator of healthy body weight, it does have its limitations. BMI is only an estimate that cannot take body composition into account. Due to a wide variety of body types as well as distribution of muscle, bone mass, and fat, BMI should be considered along with other measurements rather than being used as the sole method for determining a person’s healthy body weight.

In adults:

BMI cannot be fully accurate because it is a measure of excess body weight, rather than excess body fat. BMI is further influenced by factors such as age, sex, ethnicity, muscle mass, and body fat, and activity level, among others. For example, an older person who is considered a healthy weight, but is completely inactive in their daily life may have significant amounts of excess body fat even though they are not heavy. This would be considered unhealthy, while a younger person with higher muscle composition of the same BMI would be considered healthy. In athletes, particularly bodybuilders who would be considered overweight due to muscle being heavier than fat, it is entirely possible that they are actually at a healthy weight for their body composition. Generally, according to the CDC:

  • Older adults tend to have more body fat than younger adults with the same BMI.
  • Women tend to have more body fat than men for an equivalent BMI.
  • Muscular individuals and highly trained athletes may have higher BMIs due to large muscle mass.

In children and adolescents:

The same factors that limit the efficacy of BMI for adults can also apply to children and adolescents. Additionally, height and level of sexual maturation can influence BMI and body fat among children. BMI is a better indicator of excess body fat for obese children than it is for overweight children, whose BMI could be a result of increased levels of either fat or fat-free mass (all body components except for fat, which includes water, organs, muscle, etc.). In thin children, the difference in BMI can also be due to fat-free mass.

That being said, BMI is fairly indicative of body fat for 90-95% of the population, and can effectively be used along with other measures to help determine an individual’s healthy body weight.

BMI FORMULA

Measurement UnitsFormula and Calculation
Kilograms and meters (or centimeters)Formula: weight (kg) / [height (m)]2The formula for BMI is weight in kilograms divided by height in meters squared. If height has been measured in centimeters, divide by 100 to convert this to meters.
Pounds and inchesFormula: 703 x weight (lbs) / [height (in)]2When using English measurements, pounds should be divided by inches squared. This should then be multiplied by 703 to convert from lbs/inches2 to kg/m2.

Delhi Metro starts cleaning and maintenance work, prepares detailed social distancing norms for resumption of services

New Delhi: Protocols for social distancing and other safety norms are being worked upon for passengers for using trains and station premises whenever services are ordered to be resumed, officials said on Wednesday.

The Delhi Metro is closed since 22 March when the Janata Curfew was imposed in the wake of the novel coronavirus pandemic.

The Delhi Metro Rail Corporation (DMRC), in a statement, said it is working out detailed cleaning and maintenance procedures in view of the pandemic.

“The exercise will be extremely exhaustive as it involves cleaning and maintenance of 264 stations, over 2,200 coaches and over 1,100 escalators and 1,000 lifts etc,” it said.

Apart from this, a protocol for social distancing is being worked upon for passengers once they again start using trains and other metro premises.

However, the date of opening of the Delhi Metro has still not been finalised and will be notified to the public in due course of time, the statement said.

All systems of the metro, including signalling, electrical, rolling stock and tracks, will have to be tested in detail before services are ultimately started to ensure full safety for commuters, it said.

Delhi Metro authorities have already trained their housekeeping and other staff to adhere to enhanced safety norms to make them ready to do their jobs whenever the services are ordered to be resumed, officials had said on Tuesday.

The total number of coronavirus cases in the national capital on Wednesday mounted to 7,998 with 359 new cases, while the death toll mounted to 106.

Methylxanthines | Benefit for coronavirus infected

अमेरिका के विख्यात CNN NEWS CHANNEL के अनुसार, चीन के विख्यात कॉरोना वायरस विशेषज्ञ Dr. Li Wenliang अपनी मृत्यु के पूर्व यह कह गए हैं कि ३ केमिकल Methylxanthine, Theobromine एवं Theophylline कॉरोना वायरस को मार सकते हैं, और ये तीन कैमिकल ही चाय में पाए जाते हैं। इस लिए यदि कोई दिन में तीन कप चाय पीते हैं, तो वे कॉरोना वायरस के संक्रमित नहीं होंगे अथवा यदि कोई संक्रमित व्यक्ति चाय पीते हैं तो कुछ ही दिनों में वे संक्रमण मुक्त हो जाएंगे। इस सत्य को Dr. Li Wenliang ने कॉरोना रोगियों की Case History Study का अध्ययन कर के अविष्कार किया है।यह सत्य उजागर करने के लिए चीन सरकार ने उन्हें सजा दिया था। दुख का विषय यह है कि Dr. Li Wenliang की मृत्यु कॉरोना से अक्रान्त हो कर ही हुई थी। चाय के अन्दर जो Caffine होता है, वही Methylxanthine है और दो अन्य कैमिकल भी चाय में ही पाए जाते हैं।चीन के हुवान प्रान्त में कॉरोना रोगियों को तीन बार चाय पिलाए जाते थे, तभी आज चीन कॉरोना मुक्त हो पाया है। यह कितना सत्य है यह तो नहीं मालूम मगर इस शेयर को प्राप्त होते ही समस्त ग्रूपों में शेयर किए जा रहे हैं यदि यह सत्य होता है तो अनेकों के लिए लाभदायक सिद्ध होगा।

What are Methylxanthines?

Methylxanthines are a unique class of drug that are derived from the purine base xanthine. Xanthine is produced naturally by both plants and animals. The methylxanthines, theophylline, and dyphylline are used in the treatment of airways obstruction caused by conditions such as asthma, chronic bronchitis, or emphysema. Caffeine (present in coffee) and theobromine (present in chocolate) are also methylxanthines.

Theophylline is the most well known and most commonly used methylxanthine. At low dosages, it has an immunomodulatory, anti-inflammatory and bronchoprotective effect. Higher dosages are needed for its bronchodilator effect; however, higher dosages are often associated with toxicity.

Experts are not sure exactly how methylxanthines work but research has shown they inhibit the enzyme phosphodiesterase, antagonize adenosine receptors, and at lower dosages, their effects on histone deacetylase activity are believed to contribute to their immunomodulatory effects.

The main role of theophylline and dyphylline is to help maintain good airway control in chronic, persistent, airways disease.

Mythbusters 🛑

WHO Myth-busters

There is a lot of false information around. These are the facts.

🔢 People of all ages CAN be infected by the coronavirus. Older people, and people with pre-existing medical conditions (such as asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus.

❄ Cold weather and snow CANNOT kill the coronavirus.

☀ The coronavirus CAN be transmitted in areas with hot and humid climates

🦟 The coronavirus CANNOT be transmitted through mosquito bites.

🐶 There is NO evidence that companion animals/pets such as dogs or cats can transmit the coronavirus.

🛀 Taking a hot bath DOES NOT prevent the coronavirus

💨 Hand dryers are NOT effective in killing the coronavirus

🟣 Ultraviolet light SHOULD NOT be used for sterilization and can cause skin irritation

🌡 Thermal scanners CAN detect if people have a fever but CANNOT detect whether or not someone has the coronavirus

💦 Spraying alcohol or chlorine all over your body WILL NOT kill viruses that have already entered your body

💉 Vaccines against pneumonia, such as pneumococcal vaccine and Haemophilus influenzae type b (Hib) vaccine, DO NOT provide protection against the coronavirus.

👃 There is NO evidence that regularly rinsing the nose with saline has protected people from infection with the coronavirus.

🧄 Garlic is healthy but there is NO evidence from the current outbreak that eating garlic has protected people from the coronavirus.

💊 Antibiotics DO NOT work against viruses, antibiotics only work against bacteria.

🧪 To date, there is NO specific medicine recommended to prevent or treat the coronavirus.

What are coronaviruses, COVID-19 and how are they related to SARS?

What are coronaviruses, COVID-19 and how are they related to SARS?

What is a coronavirus?
Coronaviruses are a large family of viruses which may cause illness in animals or humans. In humans, several coronaviruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered coronavirus causes coronavirus disease COVID-19.

What is COVID-19?
COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.

Is COVID-19 the same as SARS?
No. The virus that causes COVID-19 and the one that caused the outbreak of Severe Acute Respiratory Syndrome (SARS) in 2003 are related to each other genetically, but the diseases they cause are quite different. SARS was more deadly but much less infectious than COVID-19. There have been no outbreaks of SARS anywhere in the world since 2003.

What are the symptoms of COVID-19?

What are the symptoms of COVID-19?

The most common symptoms of COVID-19 are:
🤒 fever
😴 tiredness
💨 dry cough

Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea.

These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don’t feel unwell.

Most people (about 80%) recover from the disease without needing special treatment. Around 1 out of every 6 people who gets COVID-19 becomes seriously ill and develops difficulty breathing.

Older people, and those with underlying medical problems like high blood pressure, heart problems or diabetes, are more likely to develop serious illness.

People with fever, cough and difficulty breathing should seek medical attention.

How does COVID-19 spread?

How does COVID-19 spread?

🤧 People can catch COVID-19 from others who have the virus.

💦 The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales.

🥄 These droplets land on objects and surfaces around the person.

👈 Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth.

↔ People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs out or exhales droplets. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick.

WHO is assessing ongoing research on the ways COVID-19 is spread and will continue to share updated findings.

Can the virus that causes COVID-19 be transmitted through the air?
Studies to date suggest that the virus that causes COVID-19 is mainly transmitted through contact with respiratory droplets rather than through the air.

Can COVID-19 be caught from a person who has no symptoms?
The main way the disease spreads is through respiratory droplets expelled by someone who is coughing. The risk of catching COVID-19 from someone with no symptoms at all is very low. However, many people with COVID-19 experience only mild symptoms. This is particularly true at the early stages of the disease. It is therefore possible to catch COVID-19 from someone who has, for example, just a mild cough and does not feel ill.

WHO is assessing ongoing research on the period of transmission of COVID-19 and will continue to share updated findings.

Can I catch COVID-19 from feces, animals, pets, surfaces or packages?

Can I catch COVID-19 from feces, animals, pets, surfaces or packages?

🚽 Can I catch COVID-19 from the feces of someone with the disease?

The risk of catching COVID-19 from the feces of an infected person appears to be low. While initial investigations suggest the virus may be present in feces in some cases, spread through this route is not a main feature of the outbreak. WHO is assessing ongoing research on the ways COVID-19 is spread and will continue to share new findings. Because this is a risk, however, it is another reason to clean hands regularly, after using the bathroom and before eating.

🐾 Can humans become infected with the COVID-19 from an animal source?
Coronaviruses are a large family of viruses that are common in animals. Occasionally, people get infected with these viruses which may then spread to other people. For example, SARS-CoV was associated with civet cats and MERS-CoV is transmitted by dromedary camels. Possible animal sources of COVID-19 have not yet been confirmed.

To protect yourself, such as when visiting live animal markets, avoid direct contact with animals and surfaces in contact with animals. Ensure good food safety practices at all times. Handle raw meat, milk or animal organs with care to avoid contamination of uncooked foods and avoid consuming raw or undercooked animal products.

🐶 Can I catch COVID-19 from my pet?
There is no evidence that a dog, cat or any pet can transmit COVID-19. COVID-19 is mainly spread through droplets produced when an infected person coughs, sneezes or speaks. To protect yourself clean your hands frequently and thoroughly.
