Enter the total flame distance (ft) and the total time (hrs) into the Calculator. The calculator will evaluate the Chains Per Hour.

## Chains Per Hour Formula

CPH = FD/66/T

Variables:

- CPH is the Chains Per Hour (chains/hour)
- is the total flame distance (ft)
- is the total time (hrs)

To calculate Chains Per Hour, divide the flame distance in feet by 66, then divide by the total time.

## How to Calculate Chains Per Hour?

The following steps outline how to calculate the Chains Per Hour.

- First, determine the total flame distance (ft).
- Next, determine the total time (hrs).
- Next, gather the formula from above = CPH = FD/66/T.
- Finally, calculate the Chains Per Hour.
- After inserting the variables and calculating the result, check your answer with the calculator above.
