A Body Mass Index (BMI) calculator is a tool that uses a person’s weight and height to calculate their BMI, which is a measure of body fat. The calculation is based on the formula: BMI = weight (kg) / height (m)^2. The resulting number is then placed into a BMI category, which can be used to assess whether a person is underweight, normal weight, overweight, or obese.

A BMI calculator is often used as a screening tool to assess a person’s risk for certain health conditions, such as heart disease and diabetes. Still, it is essential to note that it is not a diagnostic tool and should not be used as the sole determinant of a person’s overall health. See our calorie calculator
