BMI Calculator – FAQs

How is BMI calculated?

+

BMI equals your weight in kilograms divided by your height in metres squared (kg/m²). For imperial units, multiply pounds divided by inches squared by 703.

What is a healthy BMI range?

+

According to the World Health Organization, a BMI under 18.5 is underweight, 18.5–24.9 is normal, 25–29.9 is overweight, and 30 or above is classified as obese.

Is BMI accurate for athletes?

+

Not always. BMI does not distinguish muscle from fat, so very muscular people can register as overweight despite low body fat. Pair it with a body fat measurement for a fuller picture.
