SwitchExplanation
Formula: Grams per Liter = Grams per 12 fl oz Cup × 2.817835. 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.
Grams per Liter (g/L): a direct coffee-dose concentration format expressing how many grams of coffee are used per liter of brew water.
This route is useful when translating between per-cup coffee doses and liter-based brew targets for recipe planning and batch adjustments.
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.
