Coffee to Water Ratio Calculator
Find how much coffee to use for your water and brew strength.
Dial in your brew. A ratio of 1:16 means 1 g of coffee per 16 g (ml) of water — a common balanced strength.
The math behind it
coffee (g) = water (g) ÷ ratio. Lower ratios (1:14) are stronger; higher (1:18) are milder. About 5 g of ground coffee per tablespoon.
Worked example
500 g water at 1:16 → 31.25 g coffee (≈6.25 tbsp).
FAQ
Grams or milliliters of water?
For water they're essentially equal (1 ml ≈ 1 g), so use either.
