Does the UK still use gallons?
The UK switched fuel sales to liters in the 1990s. However, miles per gallon (imperial) remains the legal unit for car fuel economy on new vehicle labels. Road speed is in mph and distances are in miles, so imperial gallons remain embedded in UK motoring.
How does UK MPG differ from US MPG?
UK MPG uses the imperial gallon (4.546 L); US MPG uses the US gallon (3.785 L). Multiply UK MPG by 0.832 to get US MPG. A car rated 40 UK MPG ≈ 33 US MPG.

There are exactly 8 imperial pints in one imperial gallon. Each imperial pint is 568 mL, compared to 473 mL for a US pint.
Is the imperial gallon still used in Canada?
Canada officially metricated in the 1970s and fuel is sold in liters. However, some older Canadians and certain agricultural contexts still reference imperial gallons informally. Canadian and UK imperial gallons are identical (4.54609 L).
US liquid quart – Frequently Asked Questions
How many cups are in a quart?
There are 4 US cups in one US liquid quart: 1 quart = 32 fl oz and 1 cup = 8 fl oz. The full chain: 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon.
