How to Calculate BMI: Step-by-Step Formula Guide

Learn how to calculate your BMI using metric and imperial formulas to assess your weight category effectively.

50 views

To calculate BMI (Body Mass Index), you need to use the formula: BMI = weight (kg) / height^2 (m^2). If you prefer using pounds and inches, then the formula alters slightly to: BMI = (weight (lbs) / height^2 (in^2)) * 703. This calculation will yield a number that categorizes you into underweight, normal weight, overweight, or obese, based on the resulting value.

FAQs & Answers

  1. What is the standard formula to calculate BMI? The standard formula to calculate BMI is weight in kilograms divided by height in meters squared: BMI = weight (kg) / height² (m²).
  2. How do you calculate BMI using pounds and inches? To calculate BMI using pounds and inches, use the formula: BMI = (weight (lbs) / height² (in²)) × 703.
  3. What BMI range is considered healthy? A BMI between 18.5 and 24.9 is generally considered a healthy weight range for adults.
