Body Mass Index (BMI) is an individual’s weight in kilograms(kgs) divided by the square of height in meters. A high BMI can demonstrate high body fat. BMI Calculator/BMI evaluates for weight classifications that might prompt medical issues, however, it doesn’t analyze the body fatness or health of an individual person.

## How is BMI calculated?

BMI is determined the same way for both adults and children. The calculation depends on the following methods:

Measurement UnitsFormula and Calculation
Kilograms and meters (or centimeters)Formula: weight (kg) / [height (m)]2
With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared. Because height is commonly measured in centimeters, divide height in centimeters by 100 to obtain height in meters.
Example: Weight = 68 kg, Height = 165 cm (1.65 m)
Calculation: 68 Ã· (1.65)2 = 24.98
Pounds and inchesFormula: weight (lb) / [height (in)]2 x 703
Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a conversion factor of 703.
Example: Weight = 150 lbs, Height = 5â€™5â€³ (65â€³)
Calculation: [150 Ã· (65)2] x 703 = 24.96
