The word may originate from the area of fields one could seed with a barrel of grain seeds.<ref name=denstoredanske /> The acre is the equivalent Anglo-Saxon unit. Because the barrel sizes varied by country, the area unit does too. One barrel can be approximated as half a hectare.
==Per country==
===Denmark=== In Denmark, the ''tønde'' was used as an official area unit until the introduction of the metric system in 1907.<ref name=denstoredanske /> A ''tønde'' was divided in 8 ''skæpper,''<ref>{{cite book|page=[https://archive.org/details/danmarkogdetdans00kris/page/471 471]|title=Danmark Og Det Danske Folk|url=https://archive.org/details/danmarkogdetdans00kris|first=Evald|last=Rejnholdt Kristensen|year=1920|publisher=A.H. Anderson}}</ref> a ''skæppe'' was divided into 4 ''fjerdingkar,'' and a ''fjerdingkar'' into 3 ''album''.
===Norway=== A ''tønneland'' was divided in 4 mål. Nowadays, a ''mål'' corresponds to 1,000 square meters in everyday speech.
===Sweden=== The unit was officially surveyed and standardized in the 1630s, and set to 14,000 Swedish square ells, i.e. 56,000 Swedish square feet. One ''tunnland'' was divided into 56 ''kannland'', 32 ''kappland'', 6 ''skäppland,'' or 2 ''lopsland''.<ref>{{cite web|url=http://www.ne.se/uppslagsverk/encyklopedi/l%C3%A5ng/kappland|title=kappland|publisher=Nationalencyklopedin AB}}</ref>
===Finland=== In Finland, the Swedish units that were officially defined in the 1630s were used, but with Finnish names: one ''tynnyrinala'' (''tunnland'') corresponding to 32 ''kapanala'' (''kappland'') or 2 ''panninala'' (''lopsland'').
