What does the incline number on the fitness equipment mean? Is it the equivalent of incline grade on the road?

In general, treadmills offer anywhere from 0% (flat) to 15% incline. The higher the incline percentage, the more challenging your workout will be. When your treadmill is set to a 10% incline, you'll feel as though you are walking up a relatively steep hill.

The gradient or treadmill grade equating to incline percentages is a measurement of the height distance for every 100-horizontal distance. e.g. A one-in-100 gradient = 1%, and a rise of 15 meters for every 100 meters is a 15% grade. 

You may use trigonometry to measure the gradient L = √ (D2 - H2)
