I need to know how many calories I burn when I do a certain activity.

To calculate the number of calories you burn doing a certain activity, multiply your body weight in pounds by the number of calories burned per pound of body weight for that particular activity. For example, if you weigh 150 pounds and you are doing an activity that burns 300 calories per hour, then you will burn 7500 calories over the course of 8 hours.
