Enter the total amount of coffee used (g) into the French Press Ratio Calculator. The calculator will evaluate and display the amount of water needed.

## French Press Ratio Formula

The following formula is used to calculate the French Press Ratio.

W = C * 12

- Where W is the French Press Ratio (grams of water)
- C is the total amount of coffee used (g)

To calculate the amount of water for a french press, multiply the grams of coffee by 12.

## How to Calculate French Press Ratio?

The following example problems outline how to calculate French Press Ratio.

Example Problem #1:

- First, determine the total amount of coffee used (g).
- The total amount of coffee used (g) is given as: 3.

- Finally, calculate the French Press Ratio using the equation above:

W = C * 12

The values given above are inserted into the equation below and the solution is calculated:

W = C * 12 = 36 (grams of water)

Example Problem #2:** **

For this problem, the variables required are provided below:

total amount of coffee used (g) = 10
