Health & Fitness Calculators

BMI, calorie needs and other body and fitness estimates.

These calculators give general estimates about body measurements and activity: your body mass index, the calories your body uses in a day, and your running pace and speed. They are meant to help you understand numbers, not to diagnose or treat anything.

Results are for adults and vary from person to person. If you have questions about your weight, nutrition or exercise, talk to a doctor or registered dietitian.
