Arrow FOC Calculator
The formula on how to calculate Arrow Front of Center (FOC) percentage is:
Definitions:
- Arrow Length: Total length of the arrow, measured from the throat of the nock to the end of the shaft (in inches).
- Balance Point: The distance from the throat of the nock to the point where the arrow balances perfectly (in inches).
- FOC (%): The percentage of the arrow's length that the balance point is forward of its center.
Example:
- Arrow Length = 30 inches
- Balance Point = 18 inches
Step-by-step Arrow FOC Calculation:
1. Find the center of the arrow:
2. Calculate how far the balance point is forward of the center:
3. Divide the forward distance by the arrow length and multiply by 100 to get the percentage:
The arrow’s FOC is 10%.
