How do I calculate my BMI?
Body mass index (BMI) is a measurement of body fat based on height and weight. The formula for calculating BMI is given in Table 1.
Table 1. The Formula for Calculating BMI
|Measurement Units||Formula and Calculation|
|Kilograms and meters (or centimeters)|
Formula: weight (kg) / height (m)2
The 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 inches|
Formula: 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.
Example: If a person weighs 65 kg and the person’s height is 165 cm (1.65 m), the BMI is calculated as 65 ÷ (1.65)2 = 23.87 kg/m2, which means that the person has a BMI of 23.87 kg/m2 and is considered to have a healthy weight.
When calculating in pounds and inches, if a person weighs 120 lbs and the person’s height is 5 feet 6 inches (66 inches), the BMI is calculated as 703 x 120/(66)2 = 19.3 kg/m2, which means that the person has a BMI of 19.3 kg/m2 and is considered to have a healthy weight.
What is the body mass index (BMI)?
Body mass index (BMI) is a person’s weight in kilograms divided by the square of height in meters. It indicates the amount of body fat.
BMI is the most inexpensive screening tool to measure body fat. Although it does not directly measure body fat, it can be correlated with a more direct measure of body fat.
