Extreme Spread Formula
Extreme spread is the highest velocity minus the lowest. Use the same units for both, or choose units beside the calculator inputs. The example below gives 500 โ 400 = 100 fps.
ES = HV - LV
Variables:
- ES is the Extreme Spread (fps)
- HV is the highest velocity in the group (fps)
- LV is the lowest velocity in the group (fps)
To calculate an extreme spread, subtract the lowest velocity in the group from the highest velocity in the group.
How to Calculate Extreme Spread?
The following steps outline how to calculate the Extreme Spread.
- First, determine the highest velocity in the group (fps).
- Next, determine the lowest velocity in the group (fps).
- Next, gather the formula from above = ES = HV - LV.
- Finally, calculate the Extreme Spread.
- 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.
highest velocity in the group (fps) = 500
lowest velocity in the group (fps) = 400
ES = HV - LV = ?
