Grain Calculator

A simple to use app to help you determine the amount of grain in a grain bin.

With this application you can easily calculate the amount of grain stored in a round bin. With a minimum of bin diameter and wall height, the application will calculate the number of bushels or tonnes of grain. By default, the grain peak height will automatically calculate and test weight and grain moisture will be set to standard values based on the type of grain. You can adjust any of those factors to produce a more accurate result. You can save the measurements and results to your mobile device for later retrieval.

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.
