How BMI Calculator Works

The BMI Calculator works by using your weight and height to calculate your Body Mass Index. It gives you a number that indicates whether you are underweight, normal weight, overweight, or obese. This tool is useful for checking general health status.

Formula Explanation

The standard formula used to calculate BMI is:

BMI = Weight (kg) ÷ (Height (m) × Height (m))
  

• Weight = Your body weight in kilograms
• Height = Your height in meters

Example

If your weight is 75 kg and your height is 1.75 m:

BMI = 75 ÷ (1.75 × 1.75) = 24.5

A BMI of 24.5 falls into the Normal Weight range.
