Calculate BMI.
Body Mass Index (BMI) is a widely used screening method for weight categories: underweight, healthy weight, overweight, and obesity. While it's not a direct measure of body fat, it correlates with various metabolic and disease outcomes. This calculation is based on your height and weight.
BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters (kg/m²). For the imperial system, the formula is (weight in pounds / (height in inches x height in inches)) x 703.
Our free BMI Calculator makes it easy to determine your Body Mass Index. Simply enter your height and weight, and the tool will instantly calculate your BMI and tell you which category it falls into (e.g., underweight, normal, overweight).
Yes, our versatile BMI calculator supports both metric (kilograms and centimeters) and imperial (pounds and inches) units, allowing you to use the measurements you are most comfortable with.
Your BMI is a screening tool that indicates whether you have a healthy weight for your height. The result places you into a category (underweight, normal weight, overweight, obese), which can help identify potential health risks, though it should be discussed with a healthcare professional.
