How to Calculate BMI Manually: Easy Step-by-Step Guide

Learn how to calculate your BMI manually using a simple formula to assess your weight category accurately.

506 views

Calculating BMI manually involves two steps. First, divide your weight (in kilograms) by your height (in meters) squared. The formula is: BMI = weight (kg) / [height (m)]². For example, if you weigh 70 kg and are 1.75 meters tall, your BMI would be calculated as follows: 70 / (1.75 * 1.75) = 22.86. This number helps gauge whether you are underweight, normal weight, overweight, or obese.**

FAQs & Answers

  1. What is the BMI formula to calculate manually? The BMI formula is weight in kilograms divided by height in meters squared: BMI = weight (kg) / [height (m)]².
  2. How do I interpret my BMI number? BMI values categorize weight status: underweight, normal weight, overweight, or obese, helping to assess health risk.
  3. Can I use BMI to assess my health accurately? BMI is a useful screening tool for weight categories but does not measure body fat percentage or distribution.
