BODY MASS INDEX (BMI) CALCULATOR



  Back

DESCRIPTION:

This tool calculates your Body Mass Index (BMI).  BMI helps determine the weight status of adults by measuring the ratio of weight compared to height.  It can be used to evaluate weight and overall fitness.  For adults over age 20, a BMI less than 18.5 specifies you are underweight, anything between 18.5 and 24.99 is healthy, values between 25.0 and 29.99 mean you are overweight, and values greater than or equal to 30.00 indicate obesity.  Athletes may have a higher than normal BMI due to muscle.  To use the BMI calculator, specify whether you want to use English or Metric measurements, then enter your weight and height and select the Calculate button.
