Volume, Liquid & Capacity Converter

Convert metric volumes (mL, L, m³) and US / UK kitchen and fuel measures (cups, pints, gallons) in your browser.

Why do US and UK gallons differ?

A US gallon is about 3.785 L; a UK (Imperial) gallon is exactly 4.54609 L. Always pick the matching label (gal_us vs gal_uk) so cooking and fuel math stay correct.

Is 1 mL the same as 1 cm³?

Yes for practical purposes in this converter: 1 milliliter equals 1 cubic centimeter (cc).

Are kitchen cups standardized here?

US cup is treated as 8 US fl oz (~236.59 mL). The UK imperial cup option uses 10 Imperial fl oz (~284.13 mL). Recipe “cups” abroad can still vary — prefer weighing when baking precision matters.
