A coffee ratio calculator sets brew water as coffee grams times ratio. Pour-over starts at 1:16, French press at 1:15, cold brew concentrate at 1:8, and espresso at 1:2. All figures are grams, not scoops.
15 g of coffee at 1:16 uses 240 g of water. That is a typical V60 mug. French press at 1:15 with the same dose uses 225 g. Espresso at 1:2 with an 18 g dose yields 36 g in the cup.
1:16 is a common starting brew.
1:16
15 g → 240 g
Results can be wrong. This calculator is unofficial. Figures can be incomplete, rounded, or not updated. Use them at your own risk and check a tape, datasheet, ball band, or official chart before cutting, mixing, buying, or publishing. Ratio is mass only. Grind, time, and brew method still decide extraction. Espresso yield is beverage mass, not kettle water. Limits of liability are in the terms of service.
