BMI Calculator

This body mass index (BMI calculator) tool will help you find your BMI rating based on your height and mass (weight). The calculation differs when working with either imperial or metric calculations, with the metric calculation being the easiest. The metric calculation is simply your weight in kilograms divided by your height squared. This produces a result that is expressed in kilograms per meter squared. This method should be used as a rule of thumb and can differ for different genders, ethnicities, and body types. This BMI calculator will calculate your BMI, and also show which category the result fits into.
