Is BMI accurate for athletes?

BMI may overestimate body fat in muscular individuals because it cannot distinguish between muscle and fat mass. Athletes should use body composition methods like DEXA scans.

What BMI categories does WHO define?

Underweight: below 18.5, Normal: 18.5-24.9, Overweight: 25-29.9, Obese Class I: 30-34.9, Obese Class II: 35-39.9, Obese Class III: 40+.

What This Calculator Does

This BMI (Body Mass Index) calculator computes your BMI from height and weight, classifies it according to WHO categories, and shows the healthy weight range for your height. It supports both imperial and metric units.

The Formula

BMI = Weight (kg) / Height (m)^2

BMI divides weight in kilograms by the square of height in meters. For imperial units, the formula is: BMI = (Weight in lbs x 703) / (Height in inches)^2.

Step-by-Step Example

Choose unit system

Select imperial (feet/pounds) or metric (centimeters/kilograms).

Enter measurements

Input your height and weight. Example: 5 feet 10 inches, 170 lbs.

Calculate BMI

BMI = (170 x 703) / (70)^2 = 24.4.

Interpret the result

A BMI of 24.4 falls in the "Normal Weight" range (18.5-24.9).

Real-World Use Cases

Health Screening

A quick first assessment used in clinical settings to screen for weight-related health risks.

Fitness Tracking

Monitor BMI changes over time as part of a fitness or weight management program.

Public Health Research

Common Mistakes to Avoid

Using BMI as the sole indicator of health. It does not measure body fat directly and may misclassify muscular individuals.
Not accounting for age, sex, and ethnicity, which affect the relationship between BMI and health risk.
Confusing BMI categories with definitive health diagnoses. BMI is a screening tool, not a diagnostic tool.
