What is BMI?
BMI stands for Body Mass Index. It is a simple calculation that compares your weight and height. It is commonly used as a general guide to understand whether a person may be underweight, normal weight, overweight or obese.
Example
If your weight is 70 kg and your height is 175 cm:
BMI = 70 ÷ (1.75 × 1.75) = 22.86
BMI is only a general guide. It does not directly measure body fat, muscle mass or overall health.
