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)]^{2} When using English measurements, pounds should be divided by inches squared. This should then be multiplied by 703 to convert from lbs/inches^{2} to kg/m^{2}. |
