Acre to Hectare Conversion Formula
To convert acres to hectares, multiply the value by 0.404686. One acre spans 4,046.86 sq m while one hectare is 10,000 sq m, so it takes about 2.47 acres to make a hectare — handy whenever a rural MLS listing in acres must be reported in hectares for federal statistics or Quebec paperwork.
Acres and Hectares Explained
Acres (ac)
An acre (ac) is a traditional land unit equal to 4,046.86 square metres — historically the strip one furlong long by one chain wide, or 43,560 sq ft. It is the everyday measure of Canadian farms, ranches, and rural lots: a suburban house lot is around a quarter acre, a CFL football field with end zones is about two acres, and a full survey section on the Prairies is 640 acres.
Where it is used: Acres dominate rural real-estate listings, municipal assessments, and land-title documents across English Canada — especially the Prairie provinces, where the Dominion Land Survey grid defines parcels in acres — while Quebec and federal statistics lean metric.
Origin: The acre derives from Old English æcer, meaning open field, and represented a day's plowing with a medieval ox team; it was standardized as 4,840 sq yd and came to Canada with colonial land surveys, later metricated as 4,046.86 sq m.
Hectares (ha)
A hectare (ha) is the metric land unit equal to 10,000 square metres — a square 100 metres on each side, or 2.471052 acres. It is Canada's official unit for land statistics: Agriculture and Agri-Food Canada counts seeded hectares, provincial crop reports quote them, and a 100 ha property is a substantial commercial operation.
Where it is used: Hectares are standard for farmland, plantations, and official land statistics in Canada, Europe, Latin America, Australia, and UN/FAO reporting — and they are the norm in Quebec's land registry and bilingual listings.
Origin: Introduced with the French metric system from the Greek hekaton (hundred), the hectare legalizes 100 ares and became Canada's official land unit with the metrication of the 1970s — a fitting heritage for a unit with French roots.

When You Need Acres to Hectares Conversions
International Farmland Deals
A 250-acre grain farm in Saskatchewan converts to 101.17 ha for the European investment committee, whose portfolio benchmarks — price per hectare, yield per hectare — all run metric.
Commodity Yield Benchmarking
AAFC provincial averages arrive in tonnes per hectare while elevator statements and agronomists still speak bushels per acre. Converting a 5-acre canola test plot to 2.023 ha lets both datasets describe the same ground.
Ranch and Grazing Plans
Alberta and Saskatchewan ranch budgets quote carrying capacity per section — 640 acres = 259 ha — so consultants applying hectares-per-animal rules from Australia or Europe can work directly with Crown grazing leases.
Vineyard and Orchard Planting
A 12-acre vineyard in the Okanagan Valley converts to 4.86 ha before ordering stock, because European nurseries sell vines by the hectare at densities like 4,000 plants per ha.

About Our Acres to Hectares Converter
Our free online acres to hectares converter handles land measurement for Canadian farms, ranches, vineyards, and woodlots. Canada is officially metric — Statistics Canada, Agriculture and Agri-Food Canada, and Quebec's land registry all work in hectares — yet the acre remains the everyday unit in rural listings, municipal assessments, and the Dominion Land Survey grid across the Prairies. Whether you are pricing a quarter section in Saskatchewan, a hobby farm in the Fraser Valley, or a vineyard in the Okanagan or Niagara, this tool applies the exact factor of 0.404686 hectares per acre every time.
Expert Tips for Acre to Hectare Conversion
Anchor on the section: 640 acres = 259 ha exactly with this factor. Halving repeatedly gives 320 ac = 129.5 ha and 160 ac = 64.75 ha — the quarter sections Prairie surveyors and RM assessors quote.
AAFC and Statistics Canada publish yields and seeded-area data in tonnes and hectares, while elevator tickets and agronomists still talk bushels per acre; convert your acreage first (multiply by 0.404686), then scale the yield to match.
Stocking rates travel the same way: one cow-calf pair per 2 acres equals one per 0.81 ha (2 × 0.404686), a useful equivalence when reviewing grazing leases on Alberta Crown pastures.
For vineyard planning in the Okanagan or Niagara, convert before ordering vines: a 5-acre site is 2.023 ha, and European nurseries quote plants per hectare.
Mental shortcut: divide acres by 2.5 for a rough hectare figure — 160 ac gives 64 ha against the exact 64.75, close enough for a quick estimate at the auction sale.
