Dry Volume Converter
Recipes and farm stands still use pecks and bushels; grain contracts and silos use bushels or cubic meters. A bushel of wheat is not the same size as a bushel of apples by weight, but the volume unit is. Converting dry volume avoids overordering or underordering when you switch between US measures and metric.
When you need it: A recipe says "1 peck of apples" and you buy by weight. A grain contract is in bushels; your silo is in cubic meters. A farm stand sells "half bushel" — that is 17.6 L. Convert below.

Who Uses Dry Volume Conversions?
Agriculture & Grain
US and Canada trade wheat, corn, and soy in bushels. EU and many others use tonnes or cubic meters. Converting bushels to m³ or L lets you compare with metric silo capacity and international contracts.
1 bushel wheat ≈ 35.24 L = 0.0352 m³. A 100 m³ silo holds about 2,838 bushels.
Farm stands & produce
US sellers still use "a peck" or "half bushel" for apples, potatoes, or corn. Shoppers used to kg or count need a quick conversion to know how much they are buying.
1 peck = 8.81 L. A peck of apples is roughly 9–10 kg depending on variety and packing.
Recipes & cooking
Older US recipes call for "1 quart sifted flour" or "a peck of flour." Modern recipes use cups or grams. Converting dry quarts or pecks to liters (or to weight via density) avoids failed bakes.
1 US dry quart = 1.10 L. Flour: 1 L volume ≈ 500–600 g depending on sift.
Commodity & shipping
Bulk grain and feed are priced per bushel in the US. Containers and ships are in cubic meters or TEU. Converting ensures correct loading and cost per unit volume.
1,000 bushels = 35.24 m³. A 20 ft container ~33 m³ holds about 936 bushels (theoretical).
Construction & bulk materials
Sand, gravel, or mulch are sometimes sold by "scoop" or by bushel in the US; elsewhere by m³ or tonne. Dry volume conversion helps when comparing quotes.
1 m³ = 28.38 US bushels. So 10 m³ mulch ≈ 284 bushels if sold in bushels.
Did You Know?
The US bushel is defined as 2,150.42 cubic inches (exactly), which equals 35.2391 L. It was originally a volume measure for grain; the "weight per bushel" (e.g. 60 lb for wheat) varies by commodity.

A dry gallon (US) is 268.8025 cubic inches = 4.40488 L. It is larger than the US liquid gallon (3.785 L). So "gallon" always needs context: liquid or dry.

Peck and bushel are still legal units in the US for trade in certain commodities. Metric equivalents are often shown alongside (e.g. "1 bu ≈ 35.24 L") on official documents.

Common Mistakes to Avoid
Confusing dry gallon and liquid gallon
US dry gallon = 4.405 L. US liquid gallon = 3.785 L. So 1 dry gallon is about 16% larger. For flour or grain use dry; for water or milk use liquid.
Assuming "bushel" is the same everywhere
US bushel = 35.24 L. UK (imperial) bushel = 36.37 L. They differ by about 3%. For international contracts, specify US or imperial bushel.
Mixing bushel volume with bushel weight
Bushel is a volume. "Bushel weight" (e.g. 60 lb per bushel for wheat) is mass per bushel and depends on the commodity. Convert volume first; then use density if you need mass.
