Convert Ratio to Percent (slopes)

Convert slopes from Ratio to Percent automatically. Read about ratio and percent (%), and understand the conversion between ratio and percent.

About ratio. Ratio is the relation between vertical rise and horizontal run of the slope.

About percent. The percent slope is related to the vertical rise and horizontal run of the slope. As the angle approaches 90 degrees, the slope percentage approaches infinity. Do not confuse this percent measure with the percent we use to measure angles.

Conversion. Understanding the conversion between ratio and percent. The formula to convert the slope ratio to percent slope is x*100.

  1. Rise/Run (convert the ratio to the decimal fraction)
  2. Multiply the value by 100 to get percent slope

Examples:
1:5 = 0.20*100 = 20%
1:12 = 0.0833*100 = 8.33%
5:8 = 0.625*100 = 62.5%
