The Yield Per Hectare Calculator converts a harvest from a small plot to a per-hectare estimate, the standard unit for reporting crop yields worldwide. Whether you are conducting field trials, evaluating variety performance, or estimating farm yields from sample harvests, this tool provides instant conversion from any plot size to kg/ha, tonnes/ha, and an approximate bushels/acre equivalent.
Simply enter the total harvest weight from your plot and the plot area to obtain yield estimates at the standard hectare scale.
The calculator applies a simple scaling formula:
The factor 10,000 converts m² to hectares (1 ha = 10,000 m²). The bushel/acre conversion uses the wheat equivalent where 1 t/ha equals approximately 14.87 bu/ac. This conversion factor varies by crop (corn: 15.93, soybeans: 14.87, barley: 18.37).

Harvesting 5 kg from a 10 m² plot extrapolates to 5,000 kg/ha or 5.0 t/ha (about 74 bu/ac for wheat).

18 kg from 25 m² scales to 7,200 kg/ha or 7.2 t/ha, a high-yielding rice crop.
Larger plots give more reliable estimates. For field trials, a minimum of 5-10 m² per plot is recommended, with multiple replications. For on-farm yield estimates, harvest at least 1-2 m² from several representative locations in the field and average the results. Very small plots (less than 1 m²) tend to overestimate yields due to border effects.
Yes. Yields are typically reported at standard moisture contents (13% for wheat, 14% for maize, 13.5% for rice). If your harvest is at a different moisture, adjust using: Adjusted Yield = Measured Yield x (100 - Actual Moisture%) / (100 - Standard Moisture%). This ensures fair comparisons between samples harvested under different conditions.
Global average yields (approximate): wheat 3.5 t/ha, rice 4.7 t/ha, maize 5.8 t/ha, soybean 2.8 t/ha. Top-performing regions achieve much higher: wheat 8-10 t/ha in Western Europe, rice 9-10 t/ha in Australia and Egypt, maize 10-12 t/ha in the US Corn Belt. Yields vary enormously with climate, inputs, and management practices.
