What Is BMI Calculator –

BMI stands for Body Mass Index. It’s a number that tells you if your weight is suitable for your height. A mathematical formula matches your weight to your height to figure it out. The resulting number places you into one of four categories: underweight, normal weight, overweight, or obese.
Here’s the basic formula for BMI:
– BMI = Weight (kg) ÷ [Height (m) × Height (m)]
If you use pounds and inches, the formula changes slightly:
– BMI = [Weight (lbs) ÷ Height (inches)²] × 703
For example:
– If you weigh 85 kg and are 1.75 meters tall, your BMI is:
BMI = 85 ÷ (1.75 × 1.75) = 27.76

This value indicates that you’re in the “Normal Weight” category.
