Peck (UK) (pk)
Definition: An imperial dry-measure unit equal to a quarter of an imperial bushel, or exactly 9.09218 liters — larger than its US counterpart.
History: Part of the British imperial system formalized by the Weights and Measures Act of 1824, which redefined the bushel and its subdivisions on the imperial gallon rather than the older Winchester standard the US kept.
Current use: Now largely historical in everyday UK commerce, though the term survives in older agricultural records, recipes, and the idiom "a peck of trouble."
Bushel (US) (bu)
Definition: The standard US dry-measure volume unit, equal to exactly 35.2390701696 liters, historically defined from the Winchester bushel of 2,150.42 cubic inches.
History: Traces back to a English medieval grain-measure standard used in the town of Winchester, adopted by American colonists and later fixed as the US customary bushel — distinct from the British imperial bushel defined nearly two centuries later.
Current use: The everyday trading unit for grain in the United States — corn, wheat, and soybean prices are quoted per bushel on commodity markets such as the Chicago Board of Trade, even though bushels are technically a volume, not a weight, unit.

About These Parameters
- Value
- The quantity of dry goods you want to convert, expressed in the "From" unit. Accepts decimals — useful for fractional bushels or pecks.
- From Unit
- The dry-measure or metric volume unit your input value is currently measured in, such as bushels, pecks, or liters.
- To Unit
- The unit you want the result converted into. Use the swap button to flip From and To instantly.
How Dry Volume Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to the liter. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Peck (UK) → Bushel (US): multiply by 0.25801419. For example, 1 pk × 0.25801419 = 0.25801419 bu.
Why Dry and Liquid Measure Differ
A US dry quart (1.101 L) is about 16% larger than a US liquid quart (0.946 L), even though both are called "quart" — the same is true of the dry pint versus the liquid pint. This split traces back to how each was originally measured: liquids were sold by a sealed container filled to a fixed level, while dry goods like grain, apples, and berries were traditionally sold "heaped" — piled above the rim of an open measure — so the dry-measure system needed its own, separately standardized set of volumes even though English speakers reused the same unit names for both.
US vs. UK Bushels and Pecks
The US bushel (35.239 L) and the British imperial bushel (36.369 L) are not the same size — about a 3% difference — because the two countries standardized their dry-measure systems at different times. The US bushel descends from the older English Winchester measure that colonial settlers carried across the Atlantic, while Britain later redefined its own bushel and peck under the Weights and Measures Act of 1824, based on the imperial gallon. The US never adopted that later British redefinition, so American and British/Commonwealth bushels have quietly diverged ever since.
Example
1 pk equals 0.25801419 bu. For scale, a standard bushel of corn is about that same 3.8757559 pk of volume (and weighs roughly 56 lb / 25.4 kg) — so this value is about 0.26× a bushel of corn by volume.
Frequently Asked Questions
How many Bushels (US) are in 1 Peck (UK)?
1 Peck (UK) (pk) equals exactly 0.25801419 Bushels (US) (bu).
Is a dry quart the same as a liquid quart?
No. A US dry quart is 1.1012209428 liters, while a US liquid quart is 0.946352946 liters — about 16% smaller. They share a name because both trace back to English measuring traditions, but they were standardized on separate physical containers, so they should never be treated as interchangeable.
Why do farmers still use bushels?
US grain markets, contracts, and price quotes (for example, corn and wheat futures on the Chicago Board of Trade) were built around the bushel long before metric units became common, and that infrastructure is deeply embedded in agricultural pricing, storage, and logistics — converting the entire industry's unit of account to metric would be far more disruptive than simply converting bushels to other units when needed, which this page does instantly.
How accurate are these conversions?
Every conversion factor used here is the exact, standardized value for that unit (for example, 1 US bushel = exactly 35.2390701696 liters by the US customary definition) — results are limited only by floating-point display precision, not by rounded conversion constants.
