1 US cup = 8 fl oz. A standard 12-cup drip pot holds about 60 fl oz (7.5 cups).

How to use the coffee ratio calculator
- 1Enter your water
Type how much water you’re using and pick the unit — fl oz, cups, ml or liters. The calculator converts it to milliliters automatically.
- 2Set your strength
Slide from Light to Extra Strong. Balanced lands on the SCA golden ratio (1:16); bolder settings tighten the ratio for a heavier cup.
- 3Read your dose
Each brew method card shows the coffee you need in grams (weigh it for precision) and tablespoons (for a quick scoop measure).
Why brewers trust this calculator
Pour over, French press, drip, cold brew and espresso — each with its own ideal ratio, computed side by side from your water amount.
Kitchen-scale precision in grams, plus tablespoon scoop estimates when you’re traveling or between gadgets. 1 tbsp ≈ 7 g of ground coffee.
Slide toward bold and the ratio tightens the way competition brewers actually adjust — no fake “percent stronger” math.
The Specialty Coffee Association’s 1:16–1:18 range is the starting point, then each method’s immersion or pressure gets its own correction.
Enter fl oz or cups like a US kitchen, and still get exact milliliters and grams — both systems, zero mental math.
Cold brew concentrate needs a bold 1:8, and espresso runs at 1:2 — ratios the generic “coffee calculators” always get wrong.
