Enter the total engaged length (mm) and the total overall length (mm) into the Thread Percentage Calculator. The calculator will evaluate the Thread Percentage.

- Thread Engagement Length Calculator
- Thread Consumption Calculator
- Thread Pitch Calculator
- Knurling Calculator

## Thread Percentage Formula

The following two example problems outline the steps and information needed to calculate the Thread Percentage.

TP = EL / OL * 100

Variables:

- TP is the Thread Percentage (%)
- EL is the total engaged length (mm)
- OL is the total overall length (mm)

To calculate the thread percentage, divide the total engaged length by the overall length, then multiply by 100.

## How to Calculate Thread Percentage?

The following steps outline how to calculate the Thread Percentage.

- First, determine the total engaged length (mm).
- Next, determine the total overall length (mm).
- Next, gather the formula from above = TP = EL / OL * 100.
- Finally, calculate the Thread Percentage.
- 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.

total engaged length (mm) = 1.25

total overall length (mm) = 2

TP = EL / OL * 100** **= ?
