The BMI calculator uses the following formula: Weight (lb) / (Height (in))2 x 703

*Results of the BMI calculator are based on averages. A BMI below 18.5 is considered underweight, 18.5-24.9 normal, 25-29.9 overweight, and above 30 obese. Note: A BMI calculator is designed to assess relative fitness, but it does not calculate the percentage of body fat.
