Calculate Body Mass Index

Body Mass Index is a simple calculation using a person’s height and weight.
The BMI formula is: BMI = Kg / (m)2. Here are the standard BMI ranges

  • 1 inch = 2.54 centimeters
  • 1 meter = 100 cm
  • 1 pound = kilogram

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.

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)

  • 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
