Enter the offset distance (in) and the shrink per inch (in/in) into the Calculator. The calculator will evaluate the Conduit Shrink.

## Conduit Shrink Formula

CS = OD * SPI

Variables:

• CS is the Conduit Shrink (in)
• OD is the offset distance (in)
• SPI is the shrink per inch (in/in)

To calculate Conduit Shrink, multiply the offset distance by the shrink per inch.

## How to Calculate Conduit Shrink?

The following steps outline how to calculate the Conduit Shrink.

1. First, determine the offset distance (in).
2. Next, determine the shrink per inch (in/in).
3. Next, gather the formula from above = CS = OD * SPI.
4. Finally, calculate the Conduit Shrink.
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.

offset distance (in) = 30

shrink per inch (in/in) = 0.67
