Understanding US Dry Gallons to US Pecks Conversion
The US Dry Gallon (gal-dry) is a US customary dry-volume unit equal to one-eighth of a US bushel, about 4.40488 litres (268.8025 cubic inches), historically used to measure grains, berries and other loose commodities. The US Peck (pk) is the US peck, a dry measure equal to 2 US dry gallons or one-quarter of a bushel (about 8.80977 litres), traditionally used for apples and other orchard fruit. Because a peck equals two dry gallons, this conversion is a natural one at orchards and farmers' markets where apples and berries move between gallon and peck baskets.

What is the US Dry Gallon?
The US dry gallon (gal-dry) is a unit of volume used in the United States for measuring dry commodities such as grains, berries, and other agricultural produce. It is larger than the more familiar US liquid gallon.
Definition
The US dry gallon is defined as one-eighth of a US bushel, which equals 268.8025 cubic inches:
Exactly, 1 US dry gallon = 4.40488377086 liters. This is about 16.4% larger than the US liquid gallon (3.785411784 L) but slightly smaller than the imperial gallon (4.54609 L).
Origin and History
The dry gallon derives from the Winchester bushel, an English measure standardized in the late 17th century and defined as a cylinder 18.5 inches in diameter and 8 inches deep. The United States retained this bushel after independence, and the dry gallon is simply one-eighth of it. Dry measures existed because heaped commodities settle and compact differently than liquids, so a separate volume standard was practical for trade.
Law and Notable Facts
The US dry gallon is a legal US customary unit but is rarely used directly; dry commodities are more often traded in quarts, pecks, or bushels. It is not an SI unit. The UK abolished separate dry measures in 1824 when it adopted the imperial system, so the dry gallon is specifically an American measure.
Real-World Examples and Conversions
- 1 US dry gallon = 4.40488 L ≈ 268.8 cubic inches.
- 8 US dry gallons make 1 US bushel; 2 dry gallons make 1 peck.
- A US dry gallon holds about 4.6546 US dry quarts.
- 1 US dry gallon is roughly 1.164 US liquid gallons.
What is the US Peck?
The US peck is a United States customary unit of dry volume, equal to a quarter of a bushel, used for measuring fruit, vegetables, and grain. It sits between the dry gallon and the bushel in the dry-measure system.
Definition
The US peck is defined as one quarter of a US bushel, or 8 US dry quarts, equal to exactly 537.605 cubic inches.
With the bushel fixed at 2150.42 in³, a peck equals 2150.42 ÷ 4 = 537.605 in³ = 8809.77 cm³. The US peck is about 3% smaller than the imperial peck (9.09218 L).
Origin and History
The peck is an old English dry measure, attested since the 14th century and long used for grain and produce. Its US form is tied to the Winchester bushel retained from colonial England, while the imperial peck follows Britain's 1824 reform.
Law and Notable Facts
The peck endures in the tongue-twister "Peter Piper picked a peck of pickled peppers" and in US orchard sales, where apples are still sold by the peck and half-peck. It remains a legal customary unit defined via the international inch.
Real-World Examples and Conversions
- A peck of apples weighs roughly 10–12 lb and fills about 8.81 liters.
- 1 US peck = 8 US dry quarts = 16 US dry pints = 8.80977 L.
- 4 US pecks make 1 US bushel; 1 liter ≈ 0.11351 US peck.
