Enter the bore size (in) and the stroke length (in) into the Calculator. The calculator will evaluate the Bore To Stroke Ratio.

## Bore To Stroke Ratio Formula

BTS = B / S

Variables:

- BTS is the Bore To Stroke Ratio (in/in)
- B is the bore size (in)
- S is the stroke length (in)

To calculate Bore To Stroke Ratio, divide the bore size by the stroke length.

## How to Calculate Bore To Stroke Ratio?

The following steps outline how to calculate the Bore To Stroke Ratio.

- First, determine the bore size (in).
- Next, determine the stroke length (in).
- Next, gather the formula from above = BTS = B / S.
- Finally, calculate the Bore To Stroke Ratio.
- 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.

bore size (in) = 20

stroke length (in) = 10
