Slope Percentage Calculator

Convert between rise/run, slope percentage, and angle with full bidirectional solving and unit switching.

Use rise and run to compute slope percentage and angle, or provide angle/slope to solve the missing fields.

Length units support metric, imperial, and mixed display styles, while angle supports degrees, radians, gradians, and pi-radians.

The calculator keeps fields editable, so changing slope or angle updates geometric inputs in reverse too.
