Volume - Dry Converter
Convert dry volume, the measures used for grain, fruit and vegetables, between US dry units, UK units and liters. Choose two units and type a value.
Select two units to see the conversion factor.
This tool converts dry volume to dry volume. It does not give weight. A bushel of wheat and a bushel of corn have different weights. For liquid measures use the Volume Converter.
Dry Volume Formula
Every dry unit is a fixed part of the liter. Result = value × (size of source unit in liters ÷ size of target unit in liters). The US dry system is built on the bushel, which is exactly 2,150.42 cubic inches (35.23907016688 L). A peck is ¼ bushel, a dry gallon is ⅛ bushel, a dry quart is 1/32 bushel and a dry pint is 1/64 bushel. The UK bushel is 8 imperial gallons, or 36.36872 L.
What Is Dry Volume?
Dry volume is the space taken up by dry goods such as grain, beans, apples and berries. These goods are sold by the bushel, peck or dry quart, not by the liquid gallon. The SI-based base unit used here is the liter.
The US has a separate set of dry units. A US dry quart (1.101 L) is bigger than a US liquid quart (0.946 L), because the two systems come from different old measures. The names look the same but the sizes are not. That is why dry and liquid units must never be mixed.
The list has three groups. US dry: pint, quart, gallon, peck, bushel and dry barrel. UK (imperial): pint, quart, gallon, peck, bushel and the quarter (8 bushels). In the UK the dry and liquid units share the same size. Metric and cubic: milliliter, liter, hectoliter, cubic meter, cubic inch and cubic foot.
US and UK are different. The US bushel is 35.24 L and the UK bushel is 36.37 L, about 3% larger. A US dry barrel is 7,056 cubic inches (115.63 L).
Volume is not weight. A US bushel of wheat is by law 60 pounds, corn about 56 pounds and oats 32 pounds. Those weights depend on the crop and are not part of this tool.

How to Use the Dry Volume Converter
- Type the dry volume in the value box. Decimals and scientific notation such as 0.0025 or 2.5e-3 are accepted.
- Choose the From unit and the To unit.
- The result appears instantly, or press Convert Now. Very large or very small results are shown in scientific notation.
- Use Swap Units to reverse the conversion, Copy Result to copy the answer, open Show this value in all units for a full list, and Clear to start again.
Step-by-step by hand
- Find the size of each unit in the common base unit (L): 1 bu (US) = 35.23907017 L and 1 L = 1 L.
- Divide the source size by the target size to get the conversion factor: 35.23907017 ÷ 1 = 35.23907017, so 1 bu (US) = 35.23907017 L.
- Multiply by your value: 100 bu (US) × 35.23907017 = 3,523.907017 L.
Volume cannot be negative, so enter zero or a positive number.
Common Dry Volume Conversions
- Grain: 100 US bushels equals 3,523.907017 L and 3.523907017 m³.
- Orchard: 1 US peck equals 8.809767542 L, and 1 bushel is 4 pecks.
- Berries: 1 US dry pint equals 550.6104714 mL; 1 US dry quart equals 1,101.220943 mL.
- UK bushel: 1 UK bushel equals 1.032056743 US bushels.
- Dry barrel: 1 US dry barrel equals 3.281219483 US bushels and 115.6271236 L.
- Storage bin: 1,000 L equals 28.37759326 US bushels.
- UK quarter: 1 UK quarter equals 8 UK bushels.

Where and Why This Conversion Is Used
- Farming and grain trade: crop yields and prices in bushels.
- Markets: apples by the peck, berries by the dry pint.
- Storage: bin and silo size in bushels or cubic meters.
- Old recipes and records: UK pecks and bushels in historical texts.
Important Limitations
- The tool does not give weight. A bushel of one crop weighs differently from a bushel of another.
- Dry units are not liquid units. Do not use dry quarts for milk or fuel.
- US and UK bushels, pecks, quarts and pints are different sizes.
- Biblical dry measures (ephah, omer, cor and others) are left out because their size is uncertain.
