This pace calculator determines your pace for any race type activity. You can also calculate your splits, total time given distance and pace, or distance given total time and pace.

This calculator provides an estimation of calorie burn for over 600 different activities.

This calculator provides an estimation of calorie burn during exercise based on your heart rate.

This calculator estimates the amount of calories burned from walking any distance. The grade (i.e. incline or decline) of the walking surface is taken into consideration.

This calculator estimates the amount of calories burned from running any distance. The grade (i.e. incline or decline) of the running surface is taken into consideration.

These calculators convert gross calorie burn to net calorie burn, and net calorie burn to gross calorie burn.

Use this calculator to estimate the total amount of calories that you burn during an average day.

Use this calculator to estimate your basal metabolic rate (BMR). This is the amount of calories that you burn while you are at complete rest and not digesting any food.

Use this calculator to estimate your resting metabolic rate (RMR). This is the amount of calories that you burn while you are at complete rest but still digesting food.

Use this calculator to convert your exercise intensity level from a heart rate to a percentage of maximal oxygen consumption (VO2max), and vice versa.

This page actually has four separate VO2max calculators that are able to estimate your VO2max based on your resting heart rate or performance of a variety of physical exertion tests.

This calculator allows you to estimate, based on your exercise heart rate, the percentage of the total calories you burn during exercise that are derived from fat versus carbohydrates.
