About this tool
This volume converter switches instantly between metric units (milliliters, liters, cubic meters) and the cooking and imperial units used in recipes and everyday measurement — teaspoons, tablespoons, cups, pints, quarts, and gallons. Every value is computed with exact conversion factors, so results stay accurate whether you're scaling a recipe or converting an engineering spec.
One point trips people up constantly: US and UK (imperial) gallons and cups are not the same size. A US gallon is about 3.785 liters, while a UK gallon is about 4.546 liters — roughly 20% larger — and the same gap applies to cups, pints, and quarts. This tool keeps US and UK units clearly separate in the picker and the reference table below, so you always know which system a converted figure belongs to.
Frequently asked questions
Why is a US gallon different from a UK gallon?
They come from two different historical standards: the US gallon (3.785 L) is based on the old English wine gallon, while the UK (imperial) gallon (4.546 L) was standardized later and is about 20% larger. This trips people up constantly with fuel economy and recipe conversions, so this tool keeps them as clearly separate units rather than a single "gallon" option.
