To accurately count calories burned  you need to put on one of the contraptions in the picture and then use the stairs. Instead, our measurement of calories burned is explained below.

1. Steps per minute: carried out a study of 50 people with diverse ages and fitness levels.  We recorded how many steps they could climb in one minute.
2. Calories burned per minute: we utilized the MET that were formulated in the Compendium of Physical Activities . Additionally, we set our base weight at 177 lbs, the average weight of an American.

Combining our numbers and research, we arrived at 0.15 cal per step.

Limitations: We recognize that no calorie burning calculator is completely accurate.  Our goal was to find a suitable average that would be accurate for most people.
