BMI Calculator

How Does the BMI Tool Work?

The BMI tool on your website works by calculating BMI based on the following formula:

BMI= Weight(kg)​ / Height(m)2

Where:

  • Weight: The user’s body weight in kilograms (kg).
  • Height: The user’s height in meters (m). Note that the height is squared (multiplied by itself).

For example:

    • If a person weighs 70 kg and their height is 1.75 meters, the BMI would be calculated as:

BMI= 70 / 1.75 x 1.75 = 70 / 3.0625 = 22.86

This BMI of 22.86 would fall into the Normal weight category.
