What is BMI
Overview of BMI
Body mass index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms (kg) and height in metres (m).
Classifications and Limitations
The BMI is a convenient rule of thumb used to broadly categorize a person as based on tissue mass (muscle, fat, and bone) and height. Major adult BMI classifications are underweight (under 18.5 kg/m2), normal weight (18.5 to 24.9), overweight (25 to 29.9), and obese (30 or more). When used to predict an individual's health, rather than as a statistical measurement for groups, the BMI has limitations that can make it less useful than some of the alternatives, especially when applied to individuals with abdominal obesity, short stature, or high muscle mass.
Health Risk Correlations
BMIs under 20 and over 25 have been associated with higher all-cause mortality, with the risk increasing with distance from the 20–25 range.
How to Calculate BMI
The formula to calculate BMI:
BMI = Weight (kg) ÷ Height (m)²
For example, for a person who weighs 70 kilograms and is 1.75 meters tall:
BMI = 70 ÷ (1.75 × 1.75) = 22.86
This person's BMI is 22.86.

BMI Ranges
BMI Ranges for Adults
The ranges of BMI (Body Mass Index) are usually divided as follows:
- Under 18.5: Underweight
- 18.5 to 24.9: Normal Range
- 25 to 29.9: Overweight
- 30 and above: Obesity
Description of bmi ranges
These ranges are set according to adult standards and may slightly vary among different health organizations.
Also, for children and teenagers, the BMI evaluation standards consider age and gender, using percentiles to assess weight status.
