Acre to Hectare Calculator
Convert US customary acres to metric hectares (ha), square meters, crop yields (bu/acre to t/ha), and production costs ($/acre to $/ha).
Convert US Acres to Hectares (ha)
Enter land area in acres, crop yield (bu/acre), and cost per acre ($/acre).
Calculation Results
Calculated using international metric conversion standards: \text{Hectares} = \frac{\text{Acres}}{2.47105381} = \text{Acres} \times 0.40468564
Quick Summary
The Acre to Hectare Calculator converts US land area ($\text{Hectares} = \text{Acres} \times 0.404686$) to metric hectares (ha), square meters, crop yield equivalents (bu/acre to t/ha), and per-hectare costs.
Formula Explanation
\text{Hectares (ha)} = \text{Acres} \times 0.40468564 = \frac{\text{Acres}}{2.47105381}
\text{Cost per Hectare (\$)} = \text{Cost per Acre (\$)} \times 2.47105381
\text{Corn Yield (t/ha)} = \frac{\text{Yield (bu/acre)}}{15.93}How It Works
Converting farm data from US customary acres to metric hectares allows growers and agronomists to publish reports in international journals, export trade filings, and global ESG carbon credit registries. The Acre to Hectare Calculator converts area, yield, and input costs into metric standards.
Step-by-Step Worked Example
Practical Problem: A US farm reports a 100-acre corn field yielding 180 bushels/acre with production costs of $500/acre. Convert total area, yield, and cost per hectare to metric units.
- Step 1: Convert acres to hectares: $100\text{ acres} \times 0.40468564 = \mathbf{40.47\text{ metric hectares (ha)}}$.
- Step 2: Convert square meters: $40.4686 \times 10,000 = \mathbf{404,686\text{ m}^2}$.
- Step 3: Convert corn yield (180 bu/ac): $180 / 15.93 = \mathbf{11.30\text{ tonnes/hectare}}$.
- Step 4: Convert cost per hectare ($500/ac): $\$500 \times 2.4710538 = \mathbf{\$1,235.53\text{ per hectare}}$.
- Step 5: Total field production: $180\text{ bu/ac} \times 100\text{ ac} = 18,000\text{ bu} = \mathbf{457.2\text{ metric tonnes}}$.
Real-World Calculation Examples
Scenario 1: 100 Acres Corn (180 bu/ac)
Parameters: 100 acres, 180 bu/ac yield, $500/ac cost
Result: 40.47 hectares (11.30 t/ha corn yield, $1,235.53/ha cost).
Scenario 2: 160 Acre Quarter Section
Parameters: 160 acres
Result: 64.75 hectares (647,497 m² area).
Scenario 3: 50 Acres Soybeans (50 bu/ac)
Parameters: 50 acres, 50 bu/ac yield
Result: 20.23 hectares (3.36 t/ha soybean yield).
Scenario 4: 1,000 Acre Commercial Farm
Parameters: 1,000 acres
Result: 404.69 hectares (4.05 km² land area).

Frequently Asked Questions (FAQ)
How many hectares are in 1 acre?
1 US customary acre equals 0.40468564 hectares (or 4,046.86 square meters).
How do I convert acres to hectares quickly in my head?
Multiply acres by 0.4 (or divide by 2.5). For example: $100\text{ acres} \times 0.4 \approx 40\text{ hectares}$.
How do I convert corn bushels/acre to tonnes/ha?
Divide bushels/acre by 15.93 ($\text{t/ha} = \text{bu/ac} / 15.93$). For example: $180\text{ bu/ac} / 15.93 = 11.30\text{ t/ha}$.
How do I convert soybean bushels/acre to tonnes/ha?
Divide bushels/acre by 14.87 ($\text{t/ha} = \text{bu/ac} / 14.87$). For example: $50\text{ bu/ac} / 14.87 = 3.36\text{ t/ha}$.
How do I convert cost per acre to cost per hectare?
Multiply cost per acre by 2.47105 ($\text{Cost/ha} = \text{Cost/ac} \times 2.47105$).
How many hectares are in 640 acres (1 square mile)?
640 acres equals 258.999 hectares (~259 hectares).
How do I convert lbs N/acre to kg N/ha?
Multiply lbs N/acre by 1.12085 ($\text{kg N/ha} = \text{lbs N/ac} \times 1.12085$). For example: $150\text{ lbs N/ac} = 168.1\text{ kg N/ha}$.
What is a centiare and an are in metric land measure?
1 centiare = 1 m²; 1 are = 100 m²; 1 hectare = 100 ares = 10,000 m².
Why does Canada use both acres and hectares?
Canada officially uses metric hectares for government and trade, but Canadian farmers often still refer to acres for land equipment and real estate.
What is the shortcut formula for acres to square meters?
Multiply acres by 4,046.86 ($1\text{ acre} = 4,046.86\text{ m}^2$).
