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".

This Slope Calculator includes the following algorithms

*Slope Length is the square root of (rise squared plus run squared)**Angle of inclination is the tangent of (rise devided by run)**percentage is 100 multiplyed by (rise devided by run)**per mille is 1000 multiplyed by (rise devided by run)**ratio is 1 to (run devided by rise)*
