Coffee to Water Ratio Calculator for French Press

Use this calculator to determine the amount of ground coffee you need based on the amount of water and preferred strength for your French press coffee. Simply enter the amount of water in milliliters and select your desired coffee strength: Light, Medium, or Strong. Then click “Calculate” to get the weight of coffee in grams you should use.

How to Use the Calculator

  1. Enter the amount of water you plan to use in your French press in milliliters.
  2. Select your preferred strength for the coffee.
  3. Click on the “Calculate” button to get the amount of ground coffee you’ll need.

How It Calculates

The calculator works by using different coffee to water ratios depending on the selected strength:

  • Light: 1 gram of coffee per 10 ml of water
  • Medium: 1 gram of coffee per 15 ml of water
  • Strong: 1 gram of coffee per 20 ml of water
It divides the total water volume by these ratios to calculate the weight of coffee needed.

Limitations

Please note that this calculator assumes the use of a standard French press and a consistent grind size. Variations in grind size, brewing time, and personal taste may require adjustments to the calculated coffee amount.
