Understanding US Bushels to US Dry Gallons Conversion
The US bushel and the US dry gallon are both US customary dry-volume units, defined so that one bushel equals exactly 8 dry gallons. The dry gallon (about 4.405 litres) sits between the peck and the bushel in the traditional dry-measure hierarchy. This exact conversion is central to grain and produce trading, where quantities are routinely expressed in either unit.
Conversion Formula
To convert US Bushels to US Dry Gallons, multiply by this factor:

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.
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.
Frequently Asked Questions
