Elevation Grade Slope in a Percentage, Millimetres

Elevation Grade from a Percentage

This calculator will calculate the difference in elevation from a slope in a percentage and a length in metres.

Example calculation
a 6 metres long garage floor requires a 2% slope
6 * 2% =
6 * ( 2 ÷ 100)  =
6 * 0.02 = 0.12 m
the difference in elevation for this garage floor equals 0.12 metres = 120 millimetres
