How does the bmi calculator work?
Enter your weight in kilograms and height in centimeters. The calculator converts your height to meters, squares the height, and divides your weight by the squared height to calculate BMI.
Formula
BMI = Weight (kg) ÷ Height² (m)Examples

About this calculator
A BMI calculator helps you calculate Body Mass Index using your weight and height. BMI is commonly used as a general screening measure for adult weight categories.
To calculate BMI, divide your weight in kilograms by your height in meters squared. The resulting value can be compared with commonly used adult BMI categories.
For adults, a BMI below 18.5 is generally classified as underweight, 18.5 to less than 25 as normal weight, 25 to less than 30 as overweight, and 30 or higher as obesity.
BMI is a screening measure rather than a direct measurement of body fat. It does not account for factors such as muscle mass, body composition, or individual health circumstances.
Use this calculator as a general reference. For personal health decisions or interpretation of your BMI, consider discussing the result with a qualified healthcare professional.
Frequently asked questions
What is BMI?
BMI stands for Body Mass Index. It is a numerical value calculated from weight and height and is commonly used as a general screening measure for adults.
How is BMI calculated?
BMI is calculated by dividing weight in kilograms by height in meters squared.
What is a normal BMI?
For adults, a BMI from 18.5 to less than 25 is generally classified as normal weight.
What are the standard adult BMI categories?
For adults, BMI below 18.5 is generally classified as underweight, 18.5 to less than 25 as normal weight, 25 to less than 30 as overweight, and 30 or higher as obesity.
Can BMI determine body fat?
No. BMI does not directly measure body fat and does not account for factors such as muscle mass, body composition, or how fat is distributed.
Is BMI suitable for everyone?
BMI is primarily used as a general screening measure for adults. It may not be appropriate for every person or situation, so individual results should be interpreted in context.
Does height affect BMI?
Yes. BMI uses height squared in its calculation, so both weight and height affect the resulting BMI value.
Can I use BMI to diagnose a health condition?
No. BMI is a screening measure and should not be used by itself to diagnose a health condition.
