Spike's Calculators

This calculator will calculate the height difference in elevation from a slope in a percent and a run length in metres.

- run length in metres
- slope in a percent

- height difference in millimetres
- height difference in metres

6 * 2% = 6 * ( 2 ÷ 100) = 6 * 0.02 = 0.12 mthe difference in elevation for this garage floor equals 0.12 metres = 120 millimetres
