What is BMI?
Body Mass Index (BMI) is a number calculated from a person’s weight and height. It is a quick screening tool used by healthcare professionals to categorize individuals into various weight classes: underweight, normal weight, overweight, and obese.
Why is BMI Important?
Health Risk Indicator: A high or low BMI may indicate potential health risks.
Simple and Quick: Only requires your weight and height.
Universal Standard: Commonly used around the world for assessing adult weight status.
How to Calculate Your Body Mass Index (BMI) for Adults
Formula:
BMI = weight (kg) / [height (m)]²
Or if you’re using pounds and inches: BMI = (weight in pounds / [height in inches]²) x 703
Example (Metric):
If you weigh 70 kg and are 1.75 meters tall: BMI = 70 / (1.75)² = 22.86
Example (Imperial):
If you weigh 154 lbs and are 69 inches tall: BMI = (154 / (69)²) x 703 = 22.74
- BMI Categories for Adults
- BMI Range Weight Status
- Below 18.5 Underweight
- 18.5 – 24.9 Normal weight
- 25.0 – 29.9 Overweight
- 30.0 and above Obese
Note: BMI is a helpful tool but does not take muscle mass, bone density, or body composition into account.
