Body Mass Index (BMI) is a statistical measurement derived from an individual's height and weight. It serves as an accessible surrogate metric to estimate systemic body fat categories, classifying individuals into underweight, normal weight, overweight, or obese status arrays.
Our BMI Calculator supports both international metric and imperial US standard formulas:
According to standard global health metrics established by the World Health Organization (WHO), BMI classifications for adults are defined as follows:
While Body Mass Index is an excellent baseline assessment for large population studies, it has inherent limitations when evaluating individual body composition. Because BMI calculates total body mass without distinguishing between muscle tissue and adipose fat tissue, athletic individuals with high lean muscle mass may register as overweight despite having low body fat levels.
According to the World Health Organization (WHO), a healthy adult BMI ranges from 18.5 to 24.9 kg/m².
For metric units, divide weight in kilograms by height in meters squared (kg/m²). For US customary units, multiply the weight in pounds divided by height in inches squared by 703.
BMI does not measure body fat directly or account for muscle density, bone density, or fat distribution, making it less precise for athletes or elderly individuals.
