Enter the height (m) and the horizontal distance (m) into the Calculator. The calculator will evaluate the Hill Angle.

## Hill Angle Formula

HA = atan(H/HD) *57.2958

Variables:

- HA is the Hill Angle (degrees)
- H is the height (m)
- HD is the horizontal distance (m)

To calculate Hill Angle, take the arc tangent of the hill height over the hill horizontal distance.

## How to Calculate Hill Angle?

The following steps outline how to calculate the Hill Angle.

- First, determine the height (m).
- Next, determine the horizontal distance (m).
- Next, gather the formula from above = HA = atan(H/HD).
- Finally, calculate the Hill Angle.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

height (m) = 4.5

horizontal distance (m) = 7.45
