BMI Calculator: What Your Body Mass Index Really Means for Your Health

Understand what BMI is, how to calculate it, and what your results mean for your overall health and fitness goals.

Understanding Your Body Mass Index

BMI (Body Mass Index) is a simple calculation that uses your height and weight to estimate body fat and assess health risks.

How BMI is Calculated

BMI = Weight (kg) / Height (m)²

Or in imperial units:

BMI = (Weight (lbs) × 703) / Height (inches)²

What Your BMI Means

A healthy BMI generally falls between 18.5 and 24.9. However, BMI is just one indicator of health and doesn't account for:

  • Muscle mass
  • Bone density
  • Age and gender differences
  • Fat distribution
