`m = "rise"/"run"`

Enter a value for all fields

The **Rise over Run to Angle **calculator returns the angle based on rise over run.

**INSTRUCTIONS:** Enter the following:

- (
**RS**) Rise - (
**RN**) Run

**Angle (Θ):** The calculator returns the pitch as an angle in degrees, and the pitch in ratio of 12 (e.g., 2/12).

The formula for the angle based on the pitch is:

Θ = atan( rise / run)

where

- Θ = angle
- rise = vertical measurement
- run = horizontal measurement
