Explanation

Formula: Brew Ratio 1:12 = Grams per Liter × 0.012. 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.

Grams per Liter (g/L): a direct coffee-dose concentration format expressing how many grams of coffee are used per liter of brew water.

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.

This route is useful when recovering a brew ratio from a grams-per-liter dose target for recipe comparison and dialing-in work.

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.
