Body Mass Index (BMI) is a simple measure that uses your height and weight to estimate whether you are underweight, normal weight, overweight, or obese. While BMI does not directly measure body fat, it is widely used as a screening tool to identify potential weight-related health risks.
The formula is: BMI = weight (kg) / height (m)^2. For imperial units, the calculation is: BMI = (weight in lbs / height in inches^2) x 703. This calculator supports both metric and imperial units and displays a color-coded visual scale for easy interpretation. Note that BMI is a general guideline and does not account for factors like muscle mass, bone density, age, or gender.
