Tools & calculators
Educational calculators built on a versioned formula registry. Each tool shows its formula, assumptions, limitations, and sources, and produces sensible significant digits — never fake precision. Results are references, not prescriptions.

Conversions
- Yield converterConverts a crop yield between t/ha, kg/ha, lb/acre, and commodity-specific bu/acre.
- Agricultural unit convertersConvert common agricultural units: area, mass, volume (US/Imperial), temperature, application rate, plant density, bulk density, mass and bushels, and percentage and decimal fractions.
Commodity
- Moisture content converterConverts a moisture content between the wet basis and the dry basis, and reports the dry matter that goes with it.
- Dry-matter calculatorSplits a lot into its dry matter and its water from a stated moisture content.
- Commodity blending calculatorCalculates the attribute value of a two-lot blend, or the quantity of a second lot that reaches a target value.
- Packaging quantity estimatorEstimates how many uniform packages a quantity of commodity fills, and how much is left in the last one.
Post-harvest
- Water removal calculatorEstimates the water that leaves a lot, and the mass left behind, when it is dried from one moisture content to another.
- Grain moisture shrink calculatorCalculates the mathematical moisture shrink between a starting moisture and a market moisture — the water fraction alone.
- Post-harvest loss calculatorCalculates the physical (quantity) loss between two points in a post-harvest chain.
Storage
- Bulk density calculatorCalculates bulk density from mass and volume, or mass or volume from a bulk density you supply.
- Storage volume estimatorCalculates the geometric volume of a rectangular or cylindrical store, a cylinder with a conical peak, or a free-standing conical pile, and the mass it would hold at a bulk density you supply.
