How to convert the slope from mm per m length in degrees?

The slope in degrees is equal to the arctangent of the ratio of the slope height in mm to its length in m.

For example: it is necessary to convert a slope of 10 mm per 1 meter of length (10 mm / m) in degrees.

10 mm / m = 0.010 m / m = 0.010  (we convert mm in the numerator to meters) = tg α

α = arctg (0.010) = 0.57o
