SwitchExplanation
Formula: Brew Ratio 1:17 = Grams per 12 fl oz Cup × 0.047903. Why: cup-dose formats are tied to explicit water volumes such as 250 mL or 12 US fluid ounces, so the calculator first normalizes through grams per liter before applying the target format.
Grams per 12 fl oz Cup (g/12oz cup): a dose-per-cup format based on 12 US fluid ounces of water, equivalent to 354.882355 mL.
Brew Ratio 1:17: a brew-ratio format interpreted as grams of water per 1 gram of coffee, then normalized to a grams-per-liter coffee dose basis.
This route is useful when recovering a brew ratio from a per-cup coffee dose so recipes stay aligned across cup-size assumptions.
This conversion is purely multiplicative because both formats reduce through grams of coffee per liter of water, with fixed cup-size assumptions where those formats apply.
