An Imperial gallon (imp-gal) is a British volume unit of exactly 4.54609 litres, used in the UK and Commonwealth for fuel, brewing, and liquid trade. A US bushel (bu) is a US customary dry-volume unit of exactly 2150.42 cubic inches, about 35.2391 litres, used for grains, fruit, and agricultural produce. Converting Imperial gallons to US bushels relates a common British liquid measure to the American bulk dry measure, useful when comparing beverage or fuel volumes against agricultural batch capacities.

What is the Imperial Gallon?
The imperial gallon is a unit of volume used in the United Kingdom and several Commonwealth countries, most commonly for measuring fuel, beverages, and other liquids. It is noticeably larger than the US gallon.
Definition
The imperial gallon is defined as exactly 4.54609 litres:
This is an exact defining relation, not an approximation. The imperial gallon is also subdivided into 4 quarts, 8 pints, or 160 imperial fluid ounces, and it is about 20% larger than the US liquid gallon (3.78541 L).
Origin and History
The gallon descends from medieval English measures for wine and ale, which historically had several conflicting definitions. The imperial gallon was standardised by the British Weights and Measures Act of 1824, originally defined as the volume of 10 pounds of distilled water weighed in air at 62 °F. In 1985 the UK redefined it in exact metric terms as 4.54609 litres, aligning the traditional unit with the SI system.
Law and Notable Facts
The imperial gallon remains a legally recognised unit in the UK and countries such as Canada, though metric litres are now standard for most trade. A key point of confusion is that the imperial gallon (4.54609 L) differs from the US liquid gallon (3.785411784 L); the two share a name but are distinct units, so fuel-economy figures quoted in "miles per gallon" are not directly comparable between the UK and the US.
Real-World Examples and Conversions
- A UK fuel purchase of 10 imperial gallons is about 45.46 litres.
- A car rated at 50 miles per imperial gallon achieves roughly 41.6 miles per US gallon for the same efficiency.
- 1 imperial gallon of fresh water weighs about 4.546 kg (roughly 10 pounds), reflecting its original 1824 definition.
- 1 imperial gallon equals about 1.20095 US gallons.
What is the US Bushel?
The US bushel is a large United States customary unit of dry volume used chiefly in agriculture to measure grain, fruit, and other bulk crops. It is the foundation of the US dry-measure system.
Definition
The US bushel (the Winchester bushel) is defined as exactly 2150.42 cubic inches.
This equals 2150.42 × 16.387064 cm³ = 35239.07 cm³. One bushel contains 4 pecks, 32 dry quarts, or 64 dry pints. It should not be confused with the imperial bushel (36.36872 L), which is about 3% larger.
Origin and History
The Winchester bushel dates to a 1696 English statute (with roots in medieval standards kept at Winchester) and was defined as a cylinder 18.5 inches in diameter and 8 inches deep, giving 2150.42 in³. The United States adopted this measure, while Great Britain replaced it with the imperial bushel in 1824.
Law and Notable Facts
Although volumetric by definition, US grain trading uses the bushel as a weight-based unit: legal "bushel weights" fix a bushel of wheat or soybeans at 60 pounds, corn and rye at 56 pounds, and oats at 32 pounds. Commodity exchanges quote grain prices per bushel on this weight basis.
Real-World Examples and Conversions
- A bushel of shelled corn weighs 56 lb (about 25.4 kg) and occupies roughly 35.24 liters of loose volume.
- 1 US bushel = 4 pecks = 8 US dry gallons = 35.2391 L.
- 1 US bushel ≈ 0.9689 imperial bushel; 1 cubic meter ≈ 28.38 US bushels.
Frequently Asked Questions
How many US bushels are in one Imperial gallon?
One Imperial gallon equals about 0.129007 US bushels. Conversely, one US bushel holds roughly 7.75 Imperial gallons.
Why compare an Imperial gallon to a US bushel?
The Imperial gallon measures liquids while the US bushel measures dry commodities, but both express volume, so the conversion is valid. It helps when relating British liquid capacities to American agricultural volumes.
How many Imperial gallons make a US bushel?
About 7.751512 Imperial gallons fill one US bushel, since a bushel is about 35.24 litres and an Imperial gallon is 4.546 litres.
How do I reverse this conversion?
Multiply the number of US bushels by 7.751512 to get Imperial gallons. For example, 2 bu equals about 15.5 imp-gal.
What is 25 Imperial gallons in US bushels?
Multiplying 25 by 0.1290071 gives 3.22518 US bushels, a little over three bushels.
