About Volume Conversions
Volume measures three-dimensional space. Unlike length or mass, which have a single widely-used reference, volume has historically been measured with a wide variety of vessels, leading to substantial regional variation. The most common confusion today is between US and imperial (UK) gallons, which differ by about 20%.

US vs imperial
The US and imperial systems share the same names for many volume units (gallon, quart, pint, fluid ounce) but define them differently. In particular, the imperial gallon is about 20% larger than the US gallon. When following recipes or fuel-economy figures from a different country, always confirm which system is being used.
