Roof Pitch Calculator - formula for calculating degrees in metric and imperial system

Roof pitch calculator - briefly about the calculation

The Roof pitch calculator is used to calculate both the roof slope angle and the missing roof data — the projection, height, length, and slope angle of the roof. Visually, where and what values can be seen in the drawing of the calculator, which is under the form of calculation.

To calculate the angle of the roof or the data, it is enough to specify only two known values, and other values (if any) can be used for testing.
