Enter the original thickness (in) and the thickness after compaction (in) into the Percent Compaction Calculator. The calculator will evaluate the Percent Compaction.

## Percent Compaction Formula

The following two example problems outline the steps and information needed to calculate the Percent Compaction.

**PC = (OT-TC)/OT*100**

Variables:

- PC is the Percent Compaction (%)
- OT is the original thickness (in)
- TC is the thickness after compaction (in)

## How to Calculate Percent Compaction?

The following steps outline how to calculate the Percent Compaction.

- First, determine the original thickness (in).
- Next, determine the thickness after compaction (in).
- Next, gather the formula from above = PC = (OT-TC)/OT*100.
- Finally, calculate the Percent Compaction.
- 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.

original thickness (in) = 30

thickness after compaction (in) = 20

PC = (OT-TC)/OT*100** **= ?
