Coffee to Water Ratio Calculator
The Coffee to Water Ratio Calculator works out how much ground coffee you need for a given amount of water and brew strength. Enter the water amount and your preferred ratio (1:X).
Formula
Coffee (g) = Water (ml) ÷ Ratio
- A 1:16 ratio (about 60 g per litre) is a common balanced starting point.
- Lower ratios (1:14–1:15) brew stronger; higher (1:17–1:18) brew milder.
500 ml water at 1:16
Inputs
- Water: 500 ml
- Ratio (1 : X): 16
500 ÷ 16 ≈ 31 g of ground coffee for a balanced brew.
