SwitchExplanation
Formula: Grams per 12 fl oz Cup = Brew Ratio 1:15 × 23.658824. 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.
Brew Ratio 1:15: a brew-ratio format interpreted as grams of water per 1 gram of coffee, then normalized to a grams-per-liter coffee dose basis.
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.
This route is useful when turning a brew-ratio target into a per-cup coffee dose for recipe cards, single-cup brewing, and batch-size checks.
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.
