Enter your height and weight to instantly calculate your BMI and see your health category
BMI (Body Mass Index) is a common measure of whether your weight is proportionate to your height. The formula is: BMI = weight (kg) ÷ height (m)².
Enter your height (in centimeters or meters) and weight (in kilograms or pounds). The tool converts automatically and instantly shows your BMI value and category. For example, a height of 170 cm and weight of 65 kg gives BMI = 65 ÷ (1.7 × 1.7) ≈ 22.5, which is in the normal range.

BMI (Body Mass Index) measures the ratio of weight to height, calculated as weight (kg) divided by height (m) squared.
According to WHO standards, a BMI between 18.5 and 24.9 is normal for adults; below 18.5 is underweight, 25 and above is overweight, and 30 and above is obese.
BMI = weight (kg) ÷ height (m)². For example, 170 cm and 65 kg gives BMI ≈ 22.5.
