BMI Calculator
Use this BMI calculator to estimate body mass index from height and weight, with metric and imperial inputs plus a normal weight range reference.
BMI is a quick screening metric, not a diagnosis. It does not measure body fat, muscle mass, or medical risk by itself.
Example Usage
- Calculate BMI from 70 kg and 175 cm.
- Switch to imperial units and calculate BMI from pounds, feet, and inches.
- Check the normal BMI weight range for the entered height.
BMI Calculator Explained
BMI, or body mass index, is a simple screening number calculated from weight and height. The metric formula is weight in kilograms divided by height in meters squared. This calculator supports both metric and imperial inputs, shows the BMI category, and estimates the weight range that corresponds to a normal BMI for the entered height. BMI is useful for a quick reference, but it is not a medical diagnosis. It does not directly measure body fat, muscle mass, age-related factors, or individual health risk.
