What is BMI?
Body Mass Index (BMI) is a simple formula used to estimate a person's body fat based on their weight and height. It's a useful tool for categorizing individuals into different weight status categories, such as underweight, normal weight, overweight, and obesity.
How It Works
To calculate your BMI, our tool uses the following formula:
BMI = Weight (Kg) / Height (m²)
For those using pounds and inches, the formula is:
BMI = Weight (lbs) × 703 / Height (in²)
