What is BMI?
Body Mass Index (BMI) is a number calculated from your weight and height. It is a useful measure to broadly categorize a person as underweight, normal weight, overweight or obese. BMI gives a general idea of whether your weight is appropriate for your height.
How BMI is Calculated
The formula for BMI is:
BMI = weight (kg) / [height (m)]²
So, if your weight is in kilograms and your height in meters, you divide the weight by the square of the height.
Examples of BMI Ranges
- Underweight: less than 18.5
- Normal weight: 18.5 – 24.9
- Overweight: 25 – 29.9
- Obesity: 30 or greater
