BMI is a screening measure for adults. It does not account for muscle, age, sex or ethnicity, and it is not a diagnosis.
Calculated on this page. Nothing you type is sent anywhere.
How it works
BMI is weight in kilograms divided by height in metres squared. 70 kg at 1.75 m gives 70 ÷ 1.75², a BMI of about 22.9. US units are converted to metric first, which gives the same result as the 703 × lb ÷ in² formula.
The World Health Organization's adult bands are: under 18.5 underweight, 18.5 to 24.9 healthy, 25 to 29.9 overweight, and 30 or more obesity. The healthy range shown is the weight that gives a BMI of 18.5–24.9 at your height.
