BMI Calculator FAQ
What is BMI?
BMI stands for body mass index. It divides body weight in kilograms by height in meters squared to estimate whether weight is low, normal, high, or obese.
Is BMI accurate for muscular people?
BMI can overestimate risk for very muscular athletes because it does not separate fat mass from lean mass. Pair it with waist, body fat, and fitness markers.
What is a normal BMI range?
A BMI from 18.5 to 24.9 is generally considered normal for adults.
