How is BMI Calculated?

For both adults and children, BMI is calculated the same way. The calculation is based on either the Imperial System of Measurement or the Metric System of Measurement. In the United States, we use the older Imperial System of Measurement where things are measured in feet, inches and pounds.

The two formulas are:

1. Imperial System of Measurement (pounds and inches):

Using the imperial system, BMI is calculated by dividing your weight in pounds (pounds ) by your height in inches (in) squared and multiplying by a conversion factor of 703.

Formula: weight (pound ) / [height (in)]2 x 703
Example: Weight = 200 lbs, Height = 5 ft 5 inches (65 inches)
Calculation: [200 ÷ (65)2] x 703 = 33.27 BMI
2.

Using the metric system, BMI is calculated by dividing your weight in kilograms (kg) by your height in meters (m) squared. Because height is often measured in centimeters, divide height in centimeters by 100 to obtain height in meters.

Formula: weight (kg) / [height (m)]2
Example: Weight = 68 kg, Height = 165 cm (1.65 m)
Calculation: 68 ÷ (1.65)2 = 24.98 BMI
There are several online tools that may be used to calculate BMI easily and quickly. One of the more popular tools is called the BMI Chart or Body Mass Index Chart. People who are more visually oriented locate the BMI Chart easy to read and understand.
