Slope or gradient of a line describes the direction and the steepness of a line. Slope can be expressed in angles, gradients or grades.

Slope expressed as Angle

S angle = tan-1(y / x) (1)

where

S angle = angle (rad, degrees (°))

x = horizontal run (m, ft ..)

y = vertical rise (m, ft ...)

Example - Slope as Angle

Slope as angle for an elevation of 1 m over a distance of 2 m can be calculated as

S angle = tan-1((1 m)/(2 m))

= 26.6 °

Slope expressed as Grade

S grade(%) = (100 %) y / x (2)

where

S grade(%) = grade (%)

Example - Slope as Grade

Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as

S grade(%) = (1 m)/(2 m)

= 50 (%)

Slope and Roof Pitch

Roof pitch is the slope created by the rafter. You can find the roof pitch in the form of x:12 like 4/12 or 9/12.

Roof pitch on the form x:12 can be expressed in grades as

S grade(%) = (100 %) x / 12 (3)

Example - Roof Picth 4/12 as Grade

S grade(%) = (100 %) 4 / 12

= 33.3 %

Roof pitch on the form x:12 can be expressed in angles as

S angle = tan-1(x / 12) (3b)

Example - Roof Picth 4/12 as Angle

S angle = tan-1(4 / 12)

= 18.4 °
