Grain Conversion Calculator — Bushels, Tonnes, Pounds
Convert any grain quantity between US bushels, pounds, kilograms, metric tonnes, short tons, long tons, and hundredweight. Select the grain type to apply the correct USDA test weight — because one bushel of corn weighs differently from one bushel of oats.

How does this calculator work?
All grain unit conversions flow through weight in pounds: 1 bushel = test weight in lb (56 for corn, 60 for wheat/soybeans, etc.). From pounds, multiply or divide by the fixed factors to get kg, metric tonnes, short tons, or hundredweight. Select grain type so the test weight is correct.
Formula
How this is calculated
A US bushel is a volume measure (2,150.42 cubic inches), but in the grain trade it is always handled as a weight unit by applying the USDA statutory test weight. For corn the test weight is 56 lb/bu, for wheat and soybeans it is 60 lb/bu, and so on. The calculator first converts the input quantity into pounds using the appropriate test weight, then converts pounds into all other requested units using exact conversion factors: 1 kg = 2.20462 lb, 1 metric tonne = 2,204.62 lb, 1 US short ton = 2,000 lb, 1 UK long ton = 2,240 lb, 1 hundredweight (US) = 100 lb.
Test weights assume dry grain at standard moisture content: corn at 15.5%, soybeans at 13%, wheat at 13.5%. Wet grain is heavier per measured bushel, so scale weights will exceed the calculator output at above-standard moisture. Shrink tables and moisture adjustments should be applied separately for marketing or settlement purposes.
The 2025 USDA statutory test weights are used throughout — these values are defined by federal regulation and do not change year-to-year. Canola/rapeseed uses the Canada Grain Commission standard of 50 lb/bu because there is no US statutory test weight for rapeseed.
Frequently asked questions
A "bushel" in the grain trade is actually a weight: 56 lb of corn = 1 bu, but 60 lb of wheat = 1 bu. So 1,000 lb of corn equals 1,000/56 ≈ 17.86 bu, while 1,000 lb of wheat equals 1,000/60 ≈ 16.67 bu. Always select the correct grain type to get an accurate bushel conversion.
In the US, a hundredweight is exactly 100 pounds. Livestock, hay, and some specialty grains are still priced in cwt. One metric tonne = 22.046 cwt; one short ton = 20 cwt.
No. A metric tonne (t) is exactly 1,000 kg = 2,204.62 lb. A long ton (UK) is 2,240 lb ≈ 1,016 kg. A short ton (US) is 2,000 lb ≈ 907 kg. For international grain trade, metric tonnes are the standard.
