Full API documentation

Explanation

1 gallon is 3,785.41 milliliters under the same beverage volume standard, so pours, service sizes, and storage labels stay comparable.

Gallons: a US customary liquid-volume unit used for larger beverage batches and storage quantities.

Milliliters: a metric liquid-volume unit used for recipes, packaging, and measured pours.

This route is useful when translating between metric beverage volumes and US customary serving or container units for menus, prep, and packaging.

Because both measures stay in the same beverage volume system, the numbers scale directly with no density or ingredient step in the middle.
