Enter the total elevation gain and the total horizontal distance traveled from trailhead to summit to calculate the average hill grade.

## Hill Grade Formula

The following formula is used to calculate the percentage hill grade of a trail or hike.

G = EG / HD *100

- Where G is the hill grade %
- EG is the elevation gain (ft/m/ect.)
- HD is the horizontal straight line distance from head to summit

## Hill Grade Definition

A hill grade is defined as the percentage of slope on average of a certain hiking trail.

## Hill Grade Example

How to calculate a hill grade?

**First, determine the elevation gain.**Calculate the total vertical elevation gain from the trail head to the end of the hike or the summit.

**Next, determine the horizontal distance.**Calculate the straight line horizontal distance from the trailhead to end of hike.

**Finally, calculate the hill grade.**Calculate the percentage hill grade using the formula above.
