Different forms of exercise, at varying intensities, will burn different amounts of calories.  I'm a 160-pound woman and I walk at a speed of about three miles per hour; my doctor tells me this will burn about 100 calories per mile.  She also says there are 3500 calories in a pound (don't know where she got that number); therefore, I have to walk 35 miles to burn off a pound.  Whew!  Running would burn the same amount of calories in slightly less time; running up stairs or cycling uphill would burn even more (but I don't run, too painful for the joints).  There are websites where these things are calculated, you could look it up.
