How It Works

Volume measurements in the UK can be confusing because UK gallons, pints and fluid ounces differ from US equivalents. A UK pint is 568 ml while a US pint is only 473 ml. This converter distinguishes between UK (imperial) and US measures to avoid errors.

The converter supports litres, millilitres, UK gallons, US gallons, UK pints, US pints, UK fluid ounces, US fluid ounces, cups (US standard) and tablespoons. It is useful for cooking (recipe conversions), fuel economy and liquid measurements in general.

Example: Converting 2 UK gallons

2 UK gallons = 9.092 litres
2 UK gallons = 2.402 US gallons
2 UK gallons = 16 UK pints
2 UK gallons = 19.215 US pints
