A bushel of corn is a standard unit used to measure and price corn, especially in U.S. agriculture and commodity markets.

Quick Scoop: What Is a Bushel of Corn?

  • A bushel is historically a volume measure for dry goods, but in modern grain markets it’s treated as a standard weight.
  • For corn, 1 bushel is defined as 56 pounds of dry “shelled” corn (just the kernels, no cobs).
  • In metric terms, that’s about 25.4 kilograms of corn.

So when you see corn quoted at a certain price “per bushel,” that price is for 56 pounds of corn.

How It’s Used Today

  • Farm yields: Farmers often describe yield as “bushels per acre,” for example 180 bushels of corn per acre, meaning 180 × 56 pounds of corn from each acre.
  • Grain trading: Corn futures on exchanges like the Chicago Board of Trade are priced in bushels, and contracts are built around large numbers of bushels (e.g., 5,000 bushels per contract).
  • Storage & logistics: Elevators and bins are sized and managed in bushels to plan how much grain they can store and move.

Not Just “Any” Bushel

  • The bushel itself is a unit of volume in the U.S. customary system, but for each crop a standard weight per bushel is agreed on to keep trade consistent.
  • That’s why a bushel of corn is 56 pounds, while a bushel of wheat or soybeans is usually set at 60 pounds, and oats 32 pounds.

Mini Story: From Field to Price Tag

Imagine a Midwestern farmer harvesting corn in October.
Their field averages 200 bushels per acre, so each acre produces 200 × 56 = 11,200 pounds of corn.
The local grain elevator buys the corn and records everything in bushels, then sells it forward on a futures contract tied to a standardized number of bushels.
Thanks to that simple “bushel of corn” definition, everyone from farmer to trader knows exactly how much grain is being talked about at every step.

TL;DR: A bushel of corn is a standardized trade unit equal to 56 pounds (about 25.4 kg) of dry shelled corn, used to measure yields, storage, and market prices.
