Grain Calculator APP
This application uses the formulas, pack factors, and shrink factors as defined by the United States Department of Agriculture (USDA) in the Federal Crop Insurance Corporation (FDIC) Loss Adjustment Standards Handbooks. The handbooks to which I'm referring to can be found by searching the Internet for the following documents: Corn FCIC-25080, Soybeans FCIC-25440, and Small Grains FCIC-25430.
The following grain types are supported: Corn, Soybeans, Wheat, Oats, and Barley.
Measurements can be made in inches, feet, or meters, and the resulting grain volume can be displayed in bushels or tonnes. I did my best to accommodate the metric system, but let me know if I got it wrong or if I can make it better.
