Standard Moisture and Test Weight
Test weight should always be calibrated using a sample with a moisture content as close to the industry standard as possible. The table shows the industry moisture standards for some common grains.
| Standard Moisture and Test Weight | ||
| Grain | Moisture | Test Weight |
| Canola | 8.5% | 47 lb/bu (60 kg/hL) |
| Soybean | 13% | 55 lb/bu (71 kg/hL) |
| Wheat | 13.5% | 60 lb/bu (77 kg/hL) |
| Barley | 14.5 % | 48 lb/bu (62 kg/hL) |
| Corn | 15.5% | 56 lb/bu (72 kg/hL) |
| Rye | 14% | 56 lb/bu (72 kg/hL) |
| Sorghum | 13% | 56 lb/bu (72 kg/hL) |
| Oats | 13.5% | 32 lb/bu (41 kg/hL) |
| Sunflower | 10% | 25 lb/bu (32 kg/hL) |
*These measurements are based on the United States (Winchester) bushel.
