Enter the highest velocity in the group (fps) and the lowest velocity in the group (fps) into the Extreme Spread Calculator. The calculator will evaluate the Extreme Spread.

## Extreme Spread Formula

The following two example problems outline the steps and information needed to calculate the Extreme Spread.

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 by 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** **= ?
