Coffee Ratio Calculator
The Coffee Ratio Calculator turns your coffee and water amounts into a simple brew ratio (1:X), so you can dial in and repeat your ideal cup.
Formula
Ratio = Water (ml) ÷ Coffee (g), expressed as 1 : X
- A result of 1:16 means 16 ml of water per gram of coffee.
- Adjust the ratio to taste — lower for stronger, higher for milder.
30 g coffee, 500 ml water
Inputs
- Ground Coffee: 30 g
- Water: 500 ml
500 ÷ 30 ≈ 16.7, a brew ratio of about 1:16.7.
