Convert grain bushels to weight or weight to bushels using actual test weight, estimate lb/bu from a sample, and compare with commodity benchmarks.
Bushel Weight Formula
The following formula calculates total grain weight from physical US dry-bushel volume and measured test weight. A physical US dry bushel is 35.23907016688 liters. Standard trade-bushel equivalents instead divide total pounds by the commodity’s fixed reference mass.
Variables:
- BW is total grain weight (pounds)
- V is the volume (bushels)
- TW is the test weight (pounds per bushel)
To calculate the bushel weight, multiply the volume of the grain in bushels by the test weight, which is the weight of one bushel of the grain.
What is Bushel Weight?
Test weight measures bulk density as the mass filling a specified bushel volume under a prescribed filling procedure. It depends on packing, grain condition and moisture, but cannot by itself establish overall quality, moisture content or yield. This calculator’s sample-mass/volume calculation estimates bulk density; it does not perform official grain inspection.
How to Calculate Bushel Weight?
The following steps outline how to calculate the Bushel Weight.
- First, determine the volume of the grain (V) in bushels.
- Next, determine the test weight (TW) in pounds per bushel.
- Next, gather the formula from above: BW = V * TW.
- Finally, calculate the Bushel Weight (BW) in pounds.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Volume (V) = 50 bushels
Test Weight (TW) = 60 pounds per physical US bushel. Total grain weight = 50 × 60 = 3,000 pounds.
