mm/m to Degrees Slope Converter formula
degrees = atan((mm/m) / 1000) × 180 / π. This is a slope or grade conversion, not an angle-only trigonometry tool. Enter the value in the first field or use the reverse field for the opposite direction.
What this unit means
For slopes, 1 percent means 1 unit of rise per 100 units of horizontal run. 1 per mille (‰) equals 1 unit of rise per 1000 units of run, so 1‰ equals 1 mm/m. Angles in degrees are calculated with the arctangent of rise divided by run.
