Free BMI Calculator - Calculate Your Body Mass Index

Our free BMI calculator helps you calculate your Body Mass Index (BMI) instantly. BMI is a measure of body fat based on height and weight that applies to adult men and women. It's a useful tool for assessing whether you're underweight, normal weight, overweight, or obese.

BMI is calculated by dividing your weight in kilograms by the square of your height in meters. Our calculator supports both metric (kg/cm) and imperial (lbs/inches) units, making it easy for everyone to use regardless of their preferred measurement system.

BMI Categories

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 to 24.9
  • Overweight: BMI 25 to 29.9
  • Obese: BMI 30 or higher

Important Disclaimer: BMI is a screening tool and does not directly measure body fat. It may not accurately reflect body composition for athletes, elderly individuals, or those with high muscle mass. Please consult with a healthcare professional for personalized health advice.
