Measures of slope in degrees are useful for converting slope distance to horizontal distance, but percent is easier to use to calculate change in elevation. Remember that tan is slope is expressed as a ratio ... rise / run. In other words, rise (elevation change) expressed as a ratio (%) of horizontal distance.
