BMI body mass index is calculated by dividing your weight in kilograms by the square of your height in meters: BMI = kg ÷ m². In imperial units, the formula is BMI = (lbs ÷ in²) × 703. A result between 18.5 and 24.9 is classified as normal weight by the World Health Organization.

Whether you're tracking a fitness goal, preparing for a health screening, or simply curious, this page gives you the formula, the categories, and the context you need.
H2: What Is BMI (Body Mass Index)?
Body mass index, or BMI, is a numerical value derived from a person's weight and height. It's used globally by healthcare providers, researchers, and public health organizations as a quick screening tool to categorize weight status and estimate potential health risk.
According to the Centers for Disease Control and Prevention (CDC), BMI is not a direct measure of body fatness, but research has shown it correlates with direct measures of body fat in most adults. It is used as an initial screening tool not a diagnostic instrument.
The measure was developed in the 1830s by Belgian mathematician Adolphe Quetelet, which is why it was originally called the Quetelet Index. It was adopted widely in medicine in the 1970s after physiologist Ancel Keys published research validating its use in population studies.
Today, the World Health Organization (WHO) uses BMI as a global standard for classifying weight status in adults aged 18 and over.
H3: What BMI Measures and What It Does Not
BMI measures the ratio of your weight to your height. It does not directly measure body fat, muscle mass, bone density, or fat distribution. Two people with identical BMIs can have very different body compositions — a trained athlete and a sedentary individual might score similarly despite vastly different health profiles.
This is an important limitation to understand before interpreting your result.
[FEATURED SNIPPET BLOCK place here] BMI is calculated by dividing your weight in kilograms by the square of your height in meters: BMI = kg ÷ m². In imperial units, the formula is BMI = (lbs ÷ in²) × 703. A result between 18.5 and 24.9 is classified as normal weight by the World Health Organization.
H3: BMI Formula in Metric Units (kg and cm)
Formula: BMI = weight (kg) ÷ height (m)²
Note: height must be converted from centimeters to meters before calculating. Divide your height in cm by 100 to get meters. A person who is 175 cm tall = 1.75 m.
H3: BMI Formula in Imperial Units (lbs and inches)
Formula: BMI = [weight (lbs) ÷ height (in)²] × 703
The multiplier 703 is a conversion factor that adjusts the result to match the metric scale.
