So, does that mean a 50 degree slope is more than a hundred%? I am not used to percentage slopes.

You calculate percent incline by doing rise over run, then multiplying by 100. On roads, where you see percent grade the incline is usually pretty small, so the run is nearly the same as the length that you drive along the road. A 10% incline would mean that the rise is one tenth of the run. Find the angle by taking the inverse tangent of 1 over 10 = 5.71 degrees. Now, the length of the treadmill is actually the hypotenuse of this triangle. SO, you need to multiply the length of the treadmill by the sine of 5.71 degrees to get the height of the end of the treadmill. 60 inches times 0.099 = a hair under six inches. -- Blue skies.
