Grain & Post-Harvest Calculators

Practical tools for measuring grain in storage and reconciling mass as moisture is removed after harvest.

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.

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.

Incoming grain mass (mass share)

Incoming grain separates into dry matter that remains, water removed to reach target moisture, and any optional handling deduction.
