Calculate ammunition velocity extreme spread from a shot string or endpoints, solve high or low velocity, convert fps and m/s, and review mean and sample deviation.

Paste chronograph readings separated by spaces, commas, semicolons, or new lines, or choose an endpoint solve.

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.

  1. First, determine the highest velocity in the group (fps). 
  2. Next, determine the lowest velocity in the group (fps). 
  3. Next, gather the formula from above = ES = HV - LV.
  4. Finally, calculate the Extreme Spread.
  5. 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 = ?
