Enter the percentage volume of water (%) and the percentage volume of oil (%) into the Oil Water Ratio Calculator. The calculator will evaluate the Oil Water Ratio.

## Oil Water Ratio Formula

The following two example problems outline the steps and information needed to calculate the Oil Water Ratio.

**OWR = O/W**

Variables:

- OWR is the Oil Water Ratio (oil:water)
- W is the percentage volume of water (%)
- O is the percentage volume of oil (%)

## How to Calculate Oil Water Ratio?

The following steps outline how to calculate the Oil Water Ratio.

- First, determine the percentage volume of water (%).
- Next, determine the percentage volume of oil (%).
- Next, gather the formula from above = OWR = O/W.
- Finally, calculate the Oil Water 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.

percentage volume of water (%) = 60

percentage volume of oil (%) = 40

OWR = O/W** **= ?
