About Imperial gallon (imp gal)
The imperial gallon is a unit of volume defined as exactly 4.54609 liters, used in the United Kingdom, Canada, and some Commonwealth nations. It is approximately 20% larger than the US liquid gallon. Fuel economy in the UK is expressed in miles per imperial gallon. The imperial gallon divides into 8 imperial pints, each of 568 mL. The UK officially metricated fuel sales to liters in the 1980s–1990s, but miles per imperial gallon remains the legal unit for new car fuel economy labels.
UK car fuel economy figures are expressed in miles per imperial gallon. One imperial gallon equals 8 standard UK pints of beer.
About Decaliter (dal)
A decaliter (daL) is ten liters, a metric unit used in brewing, winemaking, and fuel distribution where single-liter precision is unnecessary but kiloliter scale is excessive. Common in European agricultural contexts — grain harvests, wine production statistics, and fuel depot transfers. Home brewers and small winemakers often work in decaliter batches (10–50 daL), and a standard wine barrel holds 22.5 daL (225 L).
A small homebrew batch is typically 1–5 daL (10–50 L). A standard wine barrel holds roughly 22.5 daL (225 L).
Imperial gallon – Frequently Asked Questions
How many liters are in an imperial gallon?
One imperial gallon is defined as exactly 4.54609 liters — approximately 20% more than the US liquid gallon (3.785 L).
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.
How many pints are in an imperial gallon?
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).
Decaliter – Frequently Asked Questions
What is a decaliter?
A decaliter (daL) is a metric unit equal to 10 liters. The prefix deca- means ten in the SI system. It sits between the liter and the hectoliter (100 L) in the metric volume scale.
Where is the decaliter used in practice?
The decaliter is used in European brewing, winemaking, and agricultural contexts. Home brewers use it for batch sizes (1–5 daL), and some agricultural fuel systems dispense in decaliters.
How many decaliters are in a wine barrel?
A standard Bordeaux barrel (barrique) holds 225 liters = 22.5 daL. A Burgundy barrel holds 228 liters = 22.8 daL. American oak bourbon barrels typically hold 200 L = 20 daL.
How does a decaliter compare to a US gallon?
One decaliter equals approximately 2.642 US liquid gallons. A 10-daL batch is roughly 26 US gallons — a typical homebrew fermentation vessel size.
Is the decaliter an official SI unit?
The decaliter uses the SI prefix deca- (10×), so it is a recognized metric unit. However, the hectoliter (100 L) and liter (1 L) are far more commonly used in practice.
