How to calculate Coffee to water ratio calculator?

Take the total water volume and divide it by the ratio’s second number (the X in 1:X) to determine the coffee mass.

Key formula: coffee_grams = water_volume_ml ÷ ratio

Using the Coffee to water ratio calculator calculator: an example

Example values used below: 300 ml water with a 1:16 ratio.

Step-by-step calculation:

1. Start with 300 ml of water.
2. Choose a ratio of 1:16 (one part coffee to sixteen parts water).
3. Divide 300 ÷ 16 = 18.75 → use about 18.8 g of coffee.
4. If you need ounces, convert grams to ounces: 18.75 g × 0.035274 ≈ 0.66 oz.

Frequently Asked Questions

Do I need to convert milliliters to grams for water?

No. For practical brewing purposes, 1 ml of water is effectively equal to 1 g, so you can use ml directly with the formula.

How do I make my coffee stronger or weaker?

Adjust the ratio: use a lower second number for stronger coffee (for example 1:15 or 1:14) and a higher number for a milder brew (for example 1:17 or 1:18).

What ratio is recommended for different brew methods?

Typical starting points: pour-over 1:15–1:17, drip 1:16, and espresso significantly lower; adjust to taste and grind size for best results.
