Frequently Asked Questions
What is BMI?
BMI (Body Mass Index) is a measure of body fat based on height and weight. It is calculated as weight (kg) divided by height (m) squared.
What is a normal BMI range?
A BMI between 18.5 and 24.9 is considered normal weight. Below 18.5 is underweight, 25–29.9 is overweight, and 30 or above is obese.
Is BMI accurate for everyone?
BMI is a useful screening tool but doesn't measure body fat directly. It may not be accurate for athletes, elderly people, or those with high muscle mass.
How is BMI calculated?
BMI = weight (kg) ÷ height (m)². For example, a person weighing 70kg at 1.75m has a BMI of 22.9.
