CALCULATOR
Slope Percentage Calculator
slope percentage. Example: Rise: 2 units, Positive horizontal run: 100 units gives 2 %. Horizontal run must be strictly positive; negative rise gives downhill sign. No angle conversion, road safety or accessibility-code claim. Elementary arithmetic over the accepted finite domain. No statistical population inference, supplied-data validity claim or specialist recommendation.
Horizontal run must be strictly positive; negative rise gives downhill sign. No angle conversion, road safety or accessibility-code claim. Elementary arithmetic over the accepted finite domain. No statistical population inference, supplied-data validity claim or specialist recommendation. Derivation: Express signed vertical change per horizontal change as a percentage.
Accepted inputs: Rise: -1,000,000 to 1,000,000 units; Positive horizontal run: 0.001 to 1,000,000 units.
How the calculation works
slope percent =100 rise/run
Worked example
With rise 2 units, positive horizontal run 100 units, slope percentage is 2 %.
Assumptions and limits
Horizontal run must be strictly positive; negative rise gives downhill sign. No angle conversion, road safety or accessibility-code claim. Elementary arithmetic over the accepted finite domain. No statistical population inference, supplied-data validity claim or specialist recommendation. Derivation: Express signed vertical change per horizontal change as a percentage.
