BMI formula

The body mass index formula is easy to determine. It’s a simple calculation that takes into account your weight and height.

  • The imperial BMI formula = Weight (LBS) x 703 ÷ Height (Inches²)
  • The metric BMI formula = Weight (KG) ÷ Height (Metres²)

This calculator computes the body mass index and rates it appropriately for men and women.

Children’s BMI:

For children and young people aged 2 to 18, the BMI calculator takes into account age and gender as well as height and weight.

Ideal Body Weight Calculator

There are several ways you can determine your ideal weight. The most common methods are:

  • Body Mass Index (Weight and Height)
  • Waist-to-Hip Ratio (WHR)
  • Body Fat Percentage

BMI < 18.5: Below normal weight
BMI >= 18.5 and < 25: Normal weight
BMI >= 25 and < 30: Overweight
BMI >= 35 and < 40: Class II Obesity
BMI >= 40: Class III Obesity

Waist-to-Hip Ratio (WHR)

This measurement checks how much fat is stored around your hips, waist, and buttocks. It basically compares your hip circumference with your actual waist size.

WHR = WC/HC
