Understanding US Dry Quarts to US Pecks 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 peck (pk) is a dry-volume unit equal to exactly 8 US dry quarts, or a quarter of a bushel, traditionally used for apples and produce. The exact 8-to-1 relationship makes this a natural conversion at orchards and markets that sell by the peck.

How to Convert US Dry Quarts to US Pecks
Use the fixed conversion factor between the two units to convert any quantity in a single step.
- Start with your value in US Dry Quarts: note the quantity in qt-dry that you want to convert.
- Apply the factor: multiply that quantity by 0.125, since 1 qt-dry = 0.125 pk.
- Read the result in US Pecks: the product is your value in pk.
- Worked result: 25 qt-dry × 0.125 = 3.125 pk.

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 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.
Frequently Asked Questions
How many US Pecks are in one US Dry Quart?
One US Dry Quart equals 0.125 US Pecks (pk). Multiply any quantity of US Dry Quarts by this factor to convert.
What is the formula to convert US Dry Quarts to US Pecks?
Multiply the number of US Dry Quarts by 0.125. For example, 10 US Dry Quarts = 1.25 pk.
How do I convert US Pecks back to US Dry Quarts?
Divide by 0.125, or equivalently multiply by 8. So one US Peck equals 8 US Dry Quarts.
Where is the US Dry Quarts-to-US Pecks conversion used?
The exact 8-to-1 relationship makes this a natural conversion at orchards and markets that sell by the peck.
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.
