What is yield per unit area?

Yield per unit area is the amount of crop harvested from a standard land area — for example, tonnes per hectare (t/ha) or bushels per acre (bu/ac). It represents the productivity of the field and is used as the basis for calculating total production.

How is total yield calculated?

Total Yield = Field Area × Yield per Unit Area. For example, a 50-hectare wheat field with an average yield of 3 t/ha produces 150 tonnes of wheat.

Are the crop presets actual averages?

The presets use broadly representative global averages: wheat ~3 t/ha, corn ~10 t/ha, rice ~4.5 t/ha, soybeans ~2.8 t/ha. Actual yields vary significantly by variety, climate, soil, and management. Treat presets as a starting point and enter your own measured or expected value for precise results.

How do I convert between metric and imperial units?

The results panel shows multiple unit conversions automatically. Key relationships: 1 tonne = 1,000 kg; 1 tonne/ha wheat ≈ 14.87 bushels/acre; 1 acre ≈ 0.4047 hectares. The calculator handles all conversions internally.

Is the revenue estimate accurate?

The revenue estimate is a simple gross calculation: Total Yield × Price per Unit. It does not account for costs, premiums, discounts, moisture dockage, or basis adjustments. Use it for quick projections, not final accounting.

Can I use this for any crop?

Yes. The presets cover four common crops, but you can enter any yield rate manually for any crop or commodity. The underlying formula works for any crop measured in weight per area.

Summary

Enter your field area and yield rate to calculate total harvest weight. Use crop presets for wheat, corn, rice, and soybeans. Add a crop price to estimate revenue.

How it works

Select a unit system: metric (hectares / kg or tonnes per hectare) or imperial (acres / bushels or pounds per acre).
Optionally pick a crop preset to pre-fill a typical yield rate for that crop.
Enter your field area and yield rate per unit area (or keep the preset value and adjust).
Click Calculate to see total harvest weight expressed in multiple units.
Optionally enter a price per unit to get an estimated gross revenue for the harvest.

Use cases

Estimate total grain production before harvest to plan storage and transport.
Compare expected yields between fields of different sizes using a consistent rate.
Project gross farm income by combining expected yield with current commodity prices.
Quickly convert between metric and imperial yield figures when reading international data.
Plan crop insurance coverage by knowing expected total output per field.
