Understanding the Body Mass Index (BMI) Calculator
Body Mass Index (BMI) is a measure that uses your height and weight to work out if your weight is in a healthy range. It is a simple, inexpensive, and noninvasive screening tool for identifying potential weight-related health issues in adults. Our calculator provides not just your BMI score, but also your healthy weight range, giving you actionable information.
How to Calculate BMI: The Formula
The formula for BMI depends on the unit system you are using:
- Metric Units:
BMI = weight (kg) / [height (m)]² - Imperial Units:
BMI = [weight (lbs) / (height (in))²] x 703
Interpreting Your BMI Result: The BMI Chart
The standard BMI categories, as defined by the World Health Organization (WHO), are the same for both men and women:
- Below 18.5: Underweight
- 18.5 – 24.9: Healthy Weight
- 25.0 – 29.9: Overweight
- 30.0 and Above: Obesity
Limitations of the BMI Scale
While BMI is a very useful general indicator, it is important to understand its limitations. BMI does not directly measure body fat and does not account for factors like body composition, age, or sex. For example, a very muscular athlete may have a high BMI due to the weight of their muscle mass, not excess fat. For this reason, it is often useful to use this tool in conjunction with our Body Fat Calculator to get a more complete picture of your health.
