Dry measure

Dry measure is a system of volume units, or a quantity expressed in them, traditionally used for commodities such as grain and produce.

Bushel: A unit of dry volume used chiefly for agricultural commodities. The bushel is the best-known large unit in traditional dry measure.
Volume: The amount of three-dimensional space occupied by a substance or object. Dry measure expresses capacity as volume rather than mass.
Grain trade: The buying, selling, storage, and transport of cereal grains. Grain was a central commodity measured by bushels and related units.
Weight: The force exerted on a body by gravity or another acceleration. A dry measure gives volume, not the force or mass of its contents.
Peck: A unit of dry volume equal to one quarter of a bushel in the US customary system. It shows how smaller dry units divide the bushel.
Bushel basket: A container traditionally used to hold or measure a bushel of produce or grain. A standard basket made the abstract unit usable in trade.
Agricultural market: A market where agricultural products are bought and sold. Produce sellers used capacity measures to quantify bulky goods.
Mass: A physical quantity measuring an object's inertia and, in classical physics, its amount of matter. Equal dry volumes can have different masses depending on the material.
Quart: A unit of volume used in customary and imperial measurement systems. Dry quarts provide a smaller unit in customary dry-volume tables.
Level measure: A quantity measured by filling a container and removing material above its rim. Leveling helps make bulk dry quantities comparable.
