The slope calculator allows you to calculate the angle of a slope, that could be the angle of your driveway, the pitch of a roof, the angle of a hill etc. Slope calculations are particularly useful for ensuring that water flows correctly off a surface and for reducing stress, friction and energy when moving heavy objects using a ramp.

A Slope is defined as an inclined portion of ground, and is also known as a "Grade".
It can be specified in 4 different ways, angle of inclination, percentage, per mille and as a ratio.
Note: The ratio is specified as "1 in n" rather than the mathematical "1:n".
