Slope & Grade Calculator
Calculate slope as grade percent, angle and 1:x ratio from rise and run, with ramp and drainage checks.
Formula
grade % = rise ÷ run × 100; angle = atan(rise ÷ run); ratio = 1 : (run ÷ rise)Calculate slope as grade percent, angle and 1:x ratio from rise and run, with ramp and drainage checks.
