If you weigh 100 pounds...

100 pounds = 45.359 kg

Say you go to the gym and use the stairstepper where each step is roughly 18 centimeters.

45.359(9.8)(.18) = 80.013276 W = 80.013276 J

Now say you use the stairstepper for an hour with one step per second

80.013276(3600) = 288,047.79 J

Now convert from Joules to Food Calories (Don't be confused when looking at nutrition facts... 1 food calorie is a kilocalorie)

288,047.79/4186 = 68.81 Calories are burned per hour

To burn 100 calories you would have to use the stairstepper for roughly 87 minutes..

Note: this is assuming you can continously workout on the stairstepper with one step per second.
