Converting between volume units
Converts volume between metric units (milliliters, liters, cubic meters) and US customary cooking and liquid measures (teaspoons, tablespoons, fluid ounces, cups, pints, quarts, and gallons), plus cubic feet. Handy for scaling recipes between measurement systems or converting container and shipping volumes.
Why US and UK/imperial volume units aren't interchangeable
A US gallon and a UK imperial gallon are genuinely different sizes - the UK imperial gallon is about 20% larger - which traces back to the two systems defining their base units differently centuries ago. This tool specifically uses US customary definitions throughout, which matters to know before assuming a "cup" or "gallon" value transfers directly to a UK recipe or spec sheet.
Why recipe conversion is one of the most common uses
Recipes written for a US audience use volume measures (cups, tablespoons, teaspoons) for both liquid and dry ingredients, while recipes from much of the rest of the world default to metric weight or liquid volume - converting between the two systems accurately matters for baking in particular, where ratios are more precision-sensitive than in general cooking.
Why cubic feet is included alongside cooking measures
Cubic feet serves a different, more technical use case than cooking conversions - comparing shipping container volumes, HVAC airflow calculations, or construction material quantities - included here so the same tool covers both everyday recipe scaling and more technical volume comparisons without needing a separate specialized tool.
