Whether you're on a fitness journey, looking to maintain a healthy lifestyle, or simply curious about your health metrics, BMI (Body Mass Index) is one of the easiest ways to get a quick overview of your body composition. In this post, we’ll explore what BMI is, how it's calculated, and how you can use a simple BMI Calculator to gain insight into your health.
BMI is a numerical value derived from your weight and height. It provides a rough estimate of whether you’re underweight, normal weight, overweight, or obese.
📏 Formula:
BMI = weight (kg) / [height (m)]²
This formula can also be adapted for pounds and inches:
BMI = (weight in pounds / [height in inches]²) × 703
While it doesn’t directly measure body fat, a BMI calculator offers several benefits:
