About this Tool
Body Mass Index (BMI) is a widely-used screening tool that estimates whether you have a healthy body weight for your height. This calculator also shows your healthy weight range and estimated Basal Metabolic Rate (BMR) — the calories your body burns at rest — using the Mifflin-St Jeor equation.
Common Use Cases
Health Screening
A quick first check used by professionals to flag potential weight-related risks.
Weight Goals
See exactly how many kilos to gain or lose to reach the healthy range.
Calorie Planning
Use your BMR as the baseline for diet and fitness calorie targets.
Track Progress
Re-check monthly to follow trends rather than single readings.
Pro Tips
- !
Muscle vs Fat
Athletes may show high BMI despite low body fat — BMI can't tell muscle from fat.
- !
Measure Right
Weigh yourself in the morning, measure height barefoot against a wall.
- !
BMR Is a Baseline
Total daily burn = BMR × activity level (1.2 sedentary up to 1.9 very active).
Examples
70 kg at 175 cm
A typical healthy-weight check: 70 kg and 175 cm gives a Normal BMI of 22.9.
- Convert height: 175 cm = 1.75 m, squared = 3.0625.
- Divide: 70 / 3.0625 = 22.9 BMI (Normal).
- Healthy range: 18.5 × 3.0625 = 56.7 kg to 24.9 × 3.0625 = 76.3 kg.
90 kg at 165 cm
A higher-weight check: 90 kg and 165 cm gives an Obese BMI of 33.1.
- Convert height: 165 cm = 1.65 m, squared = 2.7225.
- Divide: 90 / 2.7225 = 33.1 BMI (Obese).
- Healthy range: 18.5 × 2.7225 = 50.4 kg to 24.9 × 2.7225 = 67.8 kg.
