Understanding US Dry Quarts to US Dry Gallons Conversion
The US dry quart (qt-dry) is a US customary dry-volume unit equal to about 1.101221 litres (one-fourth of a US dry gallon), used to measure grains, berries and other dry commodities. The US dry gallon (gal-dry) equals exactly 4 US dry quarts, or about 4.40488 litres, and belongs to the US customary dry-measure family. This clean 4-to-1 relationship is used when consolidating dry quarts of grain or produce into dry gallons.

What is the US Dry Quart?
The US dry quart is a unit of volume in the United States customary system used to measure dry commodities such as grains, berries, and produce. It is distinct from the (smaller) US liquid quart and belongs to the "dry measure" family built on the bushel.
Definition
The US dry quart is defined as one thirty-second of a US bushel, or equivalently 2 US dry pints, equal to exactly 67.200625 cubic inches.
Because the bushel is fixed at exactly 2150.42 cubic inches, the dry quart equals 2150.42 ÷ 32 = 67.200625 in³ = 1101.22094 cm³. It is about 16% larger than the US liquid quart (0.946353 L), so dry and liquid quarts must never be interchanged.
Origin and History
Dry measures descend from the English Winchester bushel, standardized in the 15th century and carried to colonial America. When the United Kingdom adopted the imperial system in 1824, the US retained the older Winchester standard, which is why US dry and imperial measures diverge to this day.
Law and Notable Facts
The US dry quart remains a legal customary unit, defined by the National Institute of Standards and Technology (NIST) via the international inch of 25.4 mm. In everyday US commerce, produce like berries is often sold in "dry pint" and "dry quart" containers, though these are nominal sizes rather than precisely enforced volumes.
Real-World Examples and Conversions
- A US dry quart of blueberries holds roughly 1.10 liters, or about 0.85 lb of fruit.
- 4 US dry quarts equal 1 US dry gallon (4.40488 L) and 8 dry quarts make 1 peck.
- Converting the other way, 1 liter equals about 0.9081 US dry quart.
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
How many US Dry Gallons are in one US Dry Quart?
One US Dry Quart equals 0.25 US Dry Gallons (gal-dry). Multiply any quantity of US Dry Quarts by this factor to convert.
What is the formula to convert US Dry Quarts to US Dry Gallons?
Multiply the number of US Dry Quarts by 0.25. For example, 10 US Dry Quarts = 2.5 gal-dry.
How do I convert US Dry Gallons back to US Dry Quarts?
Divide by 0.25, or equivalently multiply by 4. So one US Dry Gallon equals 4 US Dry Quarts.
Where is the US Dry Quarts-to-US Dry Gallons conversion used?
This clean 4-to-1 relationship is used when consolidating dry quarts of grain or produce into dry gallons.
Is the US dry quart the same as a liquid quart?
No. The US dry quart (about 1.101221 L) is larger than the US liquid quart (about 0.946353 L), so the two must never be used interchangeably.
