A Slope Calculator typically calculates the slope when you know the rise (vertical distance) and run (horizontal distance). It outputs the slope as either a percentage, a ratio (e.g., rise), or an angle. The slope formula is:

Slope Formula: 

$Slope=\frac{Rise}{Run}$

The slope can be expressed as:

Percentage:

$Slope =\left(\frac{Rise}{Run}\right)\times 100$

Angle (in degrees):

$\text{Slope Angle (°)}=arctan\left(\frac{\text{Rise}}{\text{Run}}\right)\times \left(\frac{180}{\pi }\right)$
