CUP to PSI Formula
The following formula is used to calculate PSI from CUP.
PSI = -17,902 + 1.516 * CUP
PSI = -17,902 + 1.516 * CUP
- Where PSI is pounds per square inch
- CUP is the cooper units of pressure
To calculate PSI from CUP, multiply the cooper pressure units by 1.516, then subtract 17902.
What is CUP?
Definition:
CUP is a unit of pressure used in ballistics that stands for copper pressure units.
How to calculate PSI from CUP?
Example Problem:
The following example problem outlines how to calculate pounds per square inch from CUP.
First, determine the total value of the CUP.
In this example, the CUP is measured to be 15,000.
Next, the final and last step is to use the formula above to convert to PSI.
PSI = -17,902 + 1.516 * CUP
PSI = -17,902 + 1.516 * 15000
PSI = 4838 pounds per square inch
