Bushel (UK) (bu)
Definition: The British imperial dry-measure unit, equal to exactly 36.36872 liters — about 3% larger than the US bushel.
History: Established by the Weights and Measures Act of 1824, which redefined the bushel as eight imperial gallons, replacing the older Winchester bushel that Britain's American colonies had already carried overseas and kept unchanged.
Current use: Historically used across the UK and Commonwealth for grain trade; today it survives mainly in historical records, older agricultural contracts, and some Commonwealth produce markets.
Peck (US) (pk)
Definition: A US customary dry-measure unit equal to a quarter of a US bushel, or exactly 8.8097675424 liters.
History: Descended from the English Winchester measure system used since the Middle Ages for grain and produce trade, the peck was carried to America by colonial settlers and retained in US customary units even as Britain's own peck was later redefined.
Current use: Still used at US farmers' markets and orchards for selling apples, pears, and other produce by the peck rather than by weight.

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 Bushel (UK) → Peck (US): multiply by 4.128227. For example, 1 bu × 4.128227 = 4.128227 pk.
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 bu equals 4.128227 pk. For scale, a standard bushel of corn is about that same 0.96893897 bu of volume (and weighs roughly 56 lb / 25.4 kg) — so this value is about 1.03× a bushel of corn by volume.
Frequently Asked Questions
How many Pecks (US) are in 1 Bushel (UK)?
1 Bushel (UK) (bu) equals exactly 4.128227 Pecks (US) (pk).
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.
