Enter the total boost and the total pressure into the Calculator. The calculator will evaluate the Boost Pressure Ratio.

## Boost Pressure Ratio Formula

BPR = B / P

Variables:

- BPR is the Boost Pressure Ratio ()
- B is the total boost
- P is the total pressure

To calculate Boost Pressure Ratio, divide the total boost delivered by the total system pressure.

## How to Calculate Boost Pressure Ratio?

The following steps outline how to calculate the Boost Pressure Ratio.

- First, determine the total boost.
- Next, determine the total pressure.
- Next, gather the formula from above = BPR = B / P.
- Finally, calculate the Boost Pressure 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.

total boost = 70

total pressure = 5000
