Grain Weight Per Bushel Reference

How to Use This Calculator

Select a grain type from the dropdown to see its USDA standard test weight. Optionally enter a number of bushels to calculate total weight in pounds and tons. Use this as a quick reference when you need to know the standard weight for any common grain.

Why This Matters

Test weight is the official measure of grain density and quality. Grain elevators use it to determine dockage — grain below standard test weight receives a price discount. Understanding test weight helps you evaluate grain quality and estimate storage and trucking capacity.

Methodology

Test weight = Standard pounds per bushel (1.244 cubic feet) as defined by USDA. Total pounds = Test weight × Bushels. Total tons = Pounds / 2,000. Actual test weight varies by growing conditions, hybrid, and moisture at harvest.

Common Mistakes to Avoid

• Assuming actual test weight equals the standard — drought stress and early frost lower test weight significantly.
• Not knowing that soybeans and wheat share the same 60 lb/bu standard despite being very different grains.
• Ignoring test weight premiums and discounts when making marketing decisions.
• Confusing test weight (density) with moisture content — they are related but separate quality factors.
