Calculate your Body Mass Index
Body Mass Index (BMI) is a simple calculation using height and weight to estimate body fat. The formula is weight (kg) divided by height (m) squared. While BMI doesn't measure body fat directly, it's a useful screening tool for weight categories. A BMI between 18.5 and 24.9 is considered normal weight.
Enter your height and weight above using either metric (cm/kg) or imperial (ft/in/lbs) units. The calculator instantly shows your BMI score and which category you fall into. Remember that BMI is a general guideline — factors like muscle mass, age, and gender can affect the interpretation.
