A BMI calculator is a tool that allows you to estimate your body mass index (BMI), which is a measure of your body fat based on your height and weight. Your BMI can be used to determine whether you are at a healthy weight for your height.

To use a BMI calculator, you will need to input your height in either inches or centimeters and your weight in either pounds or kilograms. The calculator will then use a formula to calculate your BMI.
