Start with What Is in the Bin, Then Track What Leaves It
Post-harvest decisions need two different checks. First, measure the storage space your grain occupies. The Grain Bin Capacity Calculator estimates geometry and dry bushels from the dimensions you can measure in a round, flat-floor bin. It keeps measured density separate, because volume alone is not a reliable weight ticket.
Next, follow the grain through drying. The Grain Moisture Shrink Calculator preserves dry matter, identifies water removed to a chosen target moisture, and reports optional handling loss separately. Use the two tools together without treating a bin-volume estimate as a drying settlement.
Common Grain & Post-Harvest Tasks
Measure Bin Capacity
Turn round-bin diameter, sidewall fill depth, and a level, peaked, or inverted surface into a geometric volume and dry bushels. Add your own measured density only when you need a mass estimate.
Balance Grain Drying Mass
Separate dry matter, removed water, and optional handling loss as grain moves from incoming to target moisture. Keep physical drying shrink distinct from any commercial deduction.
At-a-Glance Measurement Checks
Bin measurement preview
Round-bin geometry (diameter and fill depth)
Measure diameter and filled sidewall depth, then describe the grain surface as level, peaked, or inverted before estimating volume.
Drying mass-balance preview
Incoming grain mass (mass share)
Incoming grain separates into dry matter that remains, water removed to reach target moisture, and any optional handling deduction.
These static previews show the inputs and mass paths each tool uses. Open a calculator for labelled values, validation and its complete text/table equivalent.
All Grain & Post-Harvest Calculators
Grain Bin Capacity Calculator
Calculate the grain volume and US dry bushels in a round, flat-floor grain bin from diameter, sidewall depth and a level, peaked or inverted surface, with mass from your measured density.
Grain Moisture Shrink Calculator
Calculate target-moisture grain mass, removed water and moisture shrink, with separate optional handling loss and an illustrative settlement using your price per tonne.
