How do you get Body Mass Index?

Answer 1

For those who use metric units:
To figure out your BMI, take your weight (in kilograms) and divide it by your height (in meters). Now take that number and divide it by your height again. Now you have your BMI!

In a formula: BMI = weight (kg) / height^2(m)


For those who use imperial units:
To figure out your BMI, take your weight (in pounds) and divide it by your height (in inches). Now take that number and divide it by your height again. Once you have that answer, multiply that by 705, and you have your BMI!

In a formula: BMI = 705 * weight (lb) / height^2 (in)
