A general reference
BMI does not tell muscle from fat, and it does not consider your age, sex, or health history. It is not a diagnosis: if you have questions about your weight, talk to a health professional.How to use it
- Choose your units: imperial (pounds, feet, and inches) or metric (kilograms and centimeters).
- Enter your weight and your height. In metric you can type centimeters (175) or meters (1.75). If you like, add your age: under 18, BMI is read differently.
- Read your BMI, your category, and your position on the scale. The tool also shows the healthy weight range for your height.
- If your weight is outside that range, you will see how many pounds or kilograms separate you from it. Remember that BMI is only a general reference.
Frequently asked questions
How do I calculate BMI in kg and cm?
Divide your weight in kilograms by your height in meters squared. If you type your height in centimeters, the tool converts it to meters first: 70 kg and 175 cm give 70 ÷ 1.75² = 22.9.
Can I type my height in meters?
Yes. A value like 1.75 is read as meters and a value like 175 as centimeters, and the tool tells you how it read your number.
Can I see my weight in pounds?
Yes. Switch to the imperial system and enter pounds, feet, and inches. The healthy range and the difference to it are then shown in pounds.
