SwitchExplanation
Formula: Grams per 250 mL Cup = Brew Ratio 1:12 × 20.833333. 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 1:12: 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 250 mL Cup (g/250mL cup): a dose-per-cup format based on a fixed 250 milliliter water volume.
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.
