How to calculate an elevation gain on treadmill?

The treadmill is stationary so there is 0 elevation gain. However if you set one up on an elevator you could gain some elevation, but you would be limited to the height of the building you are in.

C'mon man, no irony is needed. Let's say cca. 12% for about an hour on 8 km/h.

Grade is rise/run, and treadmill speed is speed along the hypotenuse, not the horizontal, so:

vertical speed = speed/sqrt(1+1/grade^2)

and elevation gain = time*speed/sqrt(1+1/grade^2)

so 0.12 grade at 8 km/h for 1 hour gives you 0.953 km of elevation gain.

If you're instead considering that speed is horizontal speed, then:

vertical speed = speed*grade, elevation gain = time*speed*grade

0.96 km with the same inputs.

There are a few websites you can google that will do the math for you.
