`theta = "atan"( "rise" / "run" )`

Enter a value for all fields

The Grade Angle calculator computes the angle associated with a rise over run.

INSTRUCTIONS: Enter the following:

• (rise) Vertical Displacement
• (run) Horizontal Displacement

Grade Angle (`theta`):  The calculator returns the grade in percentage.

The Math

The formula for the grade angle is:

        `theta = atan("rise"/"run")`

where:

• `theta` = grade angle
• rise = vertical displacement
• run = horizontal displacement
