The UK (imperial) gallon is a unit of volume equal to 160 UK fluid ounces, or exactly 4.54609 liters.
1 UK gal = 4 UK qt = 8 UK pt = 160 UK fl oz = 4.54609 L ≈ 1.201 US gal.
To liters: multiply by 4.54609. To US gallons: multiply by 1.20095. To cubic meters: multiply by 0.00454609.
UK road signs (mpg), older fuel consumption references, and some Caribbean and Middle Eastern markets that still use imperial units.
A UK gallon is about 20% larger than a US gallon. A car rated at 40 mpg (UK) gets only about 33 mpg (US).
Misinterpreting UK mpg as US mpg — UK figures look higher because the imperial gallon is larger.
UK gallon ≈ 4.55 L ≈ 1.2 US gallons. The UK gallon was defined so that 1 gallon of water = 10 pounds.
The UK fluid ounce is a unit of liquid volume equal to 1/160 of an imperial gallon, or approximately 28.413 milliliters.
1 UK fl oz = 1/20 UK pt = 1/160 UK gal ≈ 28.4131 mL. It is about 4% smaller than a US fluid ounce.
To mL: multiply by 28.4131. To US fl oz: multiply by 0.96076. To UK pints: divide by 20.
Older UK recipes, some beverage labels in Commonwealth countries, and traditional pharmaceutical dosing.
Paradoxically, the UK fluid ounce is smaller than the US fluid ounce (28.41 vs. 29.57 mL), even though UK pints and gallons are larger.
Assuming UK and US fluid ounces are the same — they differ by about 4%. This seems small but accumulates in recipes.
UK fl oz ≈ 28.4 mL, US fl oz ≈ 29.6 mL. The UK has more fl oz per pint (20) vs. US (16), but each UK fl oz is smaller.
