Percent grade on a treadmill?

Question

My friend is taking a fitness test. She'll have to run on a treadmill from 10-16% grade over a period of 10 minutes. I've seen big hills that are only 8% grade. For her test is this the incline number on the treadmill? Is the reading on the treadmill different than on a hill?

Answer 1

they should be the same unless their is something wrong with the treadmill. If she has to run a 10% grade than it will be 10 on the treadmill. It sounds like she is going to have a tough fitness test. Tell her good luck.
