About BMI Calculator

Body Mass Index (BMI) is a person's weight in kilograms divided by the square of height in meters. BMI is an inexpensive and easy screening method for weight category—underweight, healthy weight, overweight, and obesity.

BMI does not measure body fat directly, but research has shown that BMI is moderately correlated with more direct measures of body fat. Furthermore, BMI appears to be as strongly correlated with various metabolic and disease outcomes as are these more direct measures of body fatness.

BMI should be used as a screening tool but not to diagnose body fatness or health. A trained healthcare provider should perform appropriate health assessments to evaluate an individual's health status and risks.
