It comes out to about one kilo-calorie per kilogram of body weight, or one half a calorie per pound. For example, a 130-pound person burns 60 calories per hour during sleep. A 155-pounder uses 70 calories per hour.

When you ride a bicycle at 12 miles per hour, you are exercising at about ten METS or 10 times the amount of energy that you use during sleep.

Although running requires the same amount of energy per mile at any speed (110 calories per mile), riding is affected by wind resistance so the faster you ride, the more energy you use. So you have to compare running and cycling at different cycling speeds.

Dr. Edward Coyle of the University of Texas determined average values of oxygen consumption by cyclists to develop a table to estimate the approximate caloric equivalence between running and cycling.
