1. BMI (body mass index) calculator
This tool calculates your BMI. BMI estimates weight status for adults by calculating the ratio of your weight to height. Enter your height and weight then select the Calculate button. For adults over age 20, a BMI less than 18.5 specifies you are underweight, anything between 18.5 and 24.9 is healthy, values between 25 and 29.9 mean you are overweight, and values greater than or equal to 30.0 indicate obesity. Note: Athletes may have a higher than normal BMI due to muscle.
