Choose the item you want to input:Bicyclists, motorists, carpenters, roofers and others either need to calculate slope or at least must have some understanding of it.Slope, tilt or inclination can be expressed in three ways:1) As a ratio of the rise to the run (for example 1 in 20)2) As an angle (almost always in degrees)3) As a percentage called the "grade" which is the (rise ÷ run) * 100.
Of these 3 ways, slope is expressed as a ratio or a grade much more often than an actual angle and heres the reason why.Stating a ratio such as 1 in 20 tells you immediately that for every 20 horizontal units traveled, your altitude increases 1 unit.Stating this as a percentage, whatever horizontal distance you travel, your altitude increases by 5% of that distance.
Stating this as an angle of 2.8624 degrees doesnt give you much of an idea how the rise compares to the run.
