Body Mass Index (BMI) Calculator

Body mass index (BMI) is a measure of body weight in relation to height of an individual. It gives a quick assessment of whether the person has appropriate weight for height or not.

Weight is measured in kilograms and height in meters. Our BMI calculator automatically converts height from centimeters to meters. All you have to do is to enter weight in centimeters (cm) and your weight kilograms (kg).

It is measured in kilograms per meter squared (kg/m²).

The formula for BMI is: BMI=W(kg)/[H(m)]².

Where W is body weight in kilograms (kg) and H is height in Meters (m) squared.

BMI Normal Range

• BMI <18.5 kg/m² : It means you are underweight for your height.
• BMI from18.5 to 25 kg/m² : It means your weight is normal for your height.
• BMI above 25 to 29.99 kg/m²: It means you are overweight for your height.
• BMI ≥30 kg/m² : It means you have obesity.

Some guidelines further subdivide obesity into class 2 obesity and class 2 obesity based on how high is the BMI above 30.

Interpretation

You body mass index should always be between 18.5 and 25. It is dangerous to have BMI above 25 as it increases the risk of having lifestyle associated diseases such as Diabetes Mellitus, High Blood Pressure, heart diseases and Stroke.

If you are overweight or Obese, you need to consult a dietician or a qualified health care professional to plan weight loss program.
