Ares to Hectares: What You Need to Know

German wine estate management illustrates this conversion daily. The Rheingau wine region, for example, contains thousands of individual vineyard parcels ranging from 0.5 to 20 ares, registered with the Rheingau wine control authority in ares. Total area statistics for the region — about 3,200 hectares — are derived by summing all parcel areas in ares and dividing by 100. Alotment garden associations in Germany manage their total land in hectares while individual plot leases specify ares. A colony of 80 Schrebergärten, each 3.5 ares, totals 280 ares or 2.8 hectares. The municipal authority grants the land to the association in hectares; the association subletes to members in ares. The conversion links the municipal land grant to the individual membership. In Austrian cadastral surveys, large landholdings are described in hectares and individual parcels in ares. A farmer inheriting 12.4 hectares of land scattered across 23 parcels averages about 53.9 ares per parcel. The inheritance documents give the total in hectares; the individual title deeds give each parcel in ares. Converting the total back to ares (1,240 ares) and checking against the sum of parcel areas is a standard audit step. Forest management in Germany uses both units at different scales. A forest management plan might describe individual timber compartments in ares — the basic operational unit — while the overall forest holding is reported in hectares. A compartment of 35 ares is 0.35 hectares, a conveniently small unit for a single harvesting operation.

Ares to Hectares FAQ

Non-Frequently Asked Questions About Ares to Hectares

Questions nobody should ask - but someone did.

• How many Schrebergärten make a hectare?

  A typical Schrebergarten is 3.5 ares. One hectare is 100 ares. So it takes about 28.6 Schrebergärten to make a hectare — almost exactly 29 allotments. A typical Schrebergarten colony has 40 to 120 plots, so one to four colonies would fill a hectare, with room for the communal shed and the mandatory rose competition.

• If I bought one are of land per month, how long to accumulate a hectare?

  One hundred months, which is eight years and four months. At current suburban German land prices of around 200 to 500 euros per square meter, one are costs 20,000 to 50,000 euros. Accumulating a hectare would cost 2 to 5 million euros and take the better part of a decade. Property investment is a long game.

• Is there anywhere in the world where ares are used but hectares are not?

  Not really. The are and hectare are invariably used together in the same countries. You never find a country that uses ares but ignores hectares — they are part of the same metric land measurement family. The DACH countries use both; everywhere else uses neither.
