Explanation

Formula: Grams per Liter = Brew Ratio 1:15 × 66.666667. Why: both formats are normalized through grams of coffee per liter of water, so the conversion stays deterministic across brew-ratio and dose-per-volume notation.

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 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 turning a brew ratio into a grams-per-liter target so brew plans stay reproducible across different water volumes.

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.

Method & Brew Basis

Method basis: fixed coffee-dose definitions normalized through grams per liter of water.
Applied factor: 1 Brew Ratio 1:15 = 66.666667 Grams per Liter.
Consistency rule: calculator output and common-value rows use the same grams-per-liter brew basis in both directions.
