Calculate your Body Mass Index based on weight and height
Enter your weight and height to calculate BMI
BMI (Body Mass Index) is a simple measure of body fat based on your weight and height. This free online BMI calculator instantly computes your BMI and tells you what it means for your health. BMI is widely used by healthcare professionals as a screening tool to identify potential weight-related health issues. A normal BMI falls between 18.5 and 24.9 according to WHO standards. Values below 18.5 indicate underweight, while values above 25 suggest overweight, and above 30 indicate obesity. Use this tool to quickly check your BMI and understand your ideal weight range.
BMI = weight (kg) ÷ height² (m) Example: A person weighing 70 kg at 1.75 m tall BMI = 70 ÷ (1.75 × 1.75) = 70 ÷ 3.0625 = 22.9 (Normal weight)
