API, OpenAPI and WebMCP documentation

Explanation

Grams per 250 mL Cup convert into grams per liter by normalizing both brew-ratio formats through grams per liter. Formula: g/L = g/250mL cup × 4. The same relationship is used in the calculator, common values, and mirror page so recipe checks stay consistent.

This is useful when moving between ratio styles used for filter coffee, immersion brews, batch recipes, or cafe prep sheets while keeping one fixed dose basis.

Method & Brew Basis

Method basis: fixed cup-volume assumptions normalized through grams of coffee per liter of water.
Applied factor: 1 Grams per 250 mL Cup = 4 Grams per Liter.
Consistency rule: calculator output and common-value rows use the same grams-per-liter brew basis in both directions.
