Coffee Ratios: Why Weighing Beats Scooping
Scoops vary with grind and bean, but grams do not. A fixed ratio turns a good cup into a repeatable one.
What is the Coffee Ratio Calculator?
Brew ratio is coffee to water by weight, and it decides whether a cup tastes thin, balanced, or heavy. This calculator works out the missing side: enter coffee to get water, or water to get coffee, for the ratio you choose. A kitchen scale gives the most reliable results.
How to use it
- Choose whether you know the coffee or the water amount.
- Enter that amount in grams.
- Pick a ratio and click Calculate Ratio.
Worked example
20 g of coffee at 1:16 needs 320 g of water.
How much water does 20 g of coffee need at 1:16?
320 g of water, since each gram of coffee pairs with 16 g of water.
Frequently asked questions
What ratio suits a pour-over?
Around 1:15 to 1:17 gives a balanced cup. Stronger tastes sit near 1:14, lighter ones near 1:17.
Does water weight equal water volume?
Almost. One gram of water is about one millilitre, so grams and millilitres can be used interchangeably here.
