I do a lot of hill climbing and knowing the steepness of hills is an important aspect of gauging the difficult of a climb. Other than the laborious task of measuring distances and elevations on a topo map, there aren't a lot of easy ways to do this. The Sky-Mounti inclinometer is the least expensive and easiest method I've found. Its main limitation is that judging steepness to within one percent is sometimes difficult, since the tick marks on the level are very close together and the bubble shifts slightly with minor accelerations and decelerations. But plus or minus a percent or so, it works great. Alternatively, I've found a good cyclometer/altimeter, the VDO MC 1.0+, that gives percent grade as a readout and seems to work very well. But it costs >$100.
