Scandinavian mile

The last Danish mile was standardized in 1683 by Ole Rømer to , equivalent to 4 minutes of latitude, and was also used in Prussia, see German miles. Before that each region had its own lengths. For instance Zealand mile of 17,600 alen or 11.13 km. == Swedish mile ==

County miles In early history, Sweden had various regional miles with their own measurements. Later on, such miles were generally defined by county (, "county miles"). Some noteworthy county miles are: • Dala mile – • Finnish mile () – around • Småland mile – around • Uppland mile – = 3,600 Swedish rods = 6,000 Swedish fathoms = 18,000 Swedish ells = 36,000 Swedish feet • Västgöta mile – around • Ångermanland mile – = 6,666 Swedish fathoms Unit mile In 1649 the Swedish government made the Uppland mile the de facto Swedish mile, or "unit mile" (), for all of Sweden, also known as "land mile" or "long mile". It could be divided into four "quarter ways" (, "firkin way"), describing a quarter of a unit mile. Old regional miles still persisted across Sweden in the 18th century and regional variations of rod, fathom, ell and foot also caused regional variation to the unit mile. This became apparent with the Swedish-Norwegian union in 1814, were the different definitions of foot in made the unit mile in Norway. Metric mile When the metric system was introduced, the '''' was redefined to be exactly . The metric system was introduced in Norway in 1875 and Sweden in 1889, after a decision by the parliament in 1876 and a ten-year transition period from 1879. When the Russian Empire introduced the metric system in 1887, the Grand Duchy of Finland decided to redefine the old Finnish mile peninkulma (, ), which was based on the Swedish mile, to also be . In Finland, however, it has been much less in use than in Sweden and Norway. == Usage ==

The ' is currently not used on road signs, and kilometre is the standard for most formal written distances. However, it is very common in colloquial speech, including 5 km, which is referred to in Swedish as "half a '" (). The ' has however not lost all formal uses. Various tax deductions, for example regarding distance travelled for business purposes, are measured in ' by the Swedish Tax Agency (). It is also used in the most common unit for measuring vehicle fuel consumption – "litres per '" – and in Sweden in second-hand car advertisements, where odometer readings are often quoted in ' though the car itself records kilometres. Metric farsang In Iran and Turkey, an indigenous unit of measurement, equivalent to the Scandinavian mile, is used, known as farsang. Originally a Persian unit of measurement, equivalent to the European league, known as parasang (4.8 or 5.6 km). It was redefined in Iran as 10 kilometres on 31 May 1926. The older Iranian farsang survives regionally as farsakh-song. In Turkey there is a "light farsang" defined as , similar to the Scandinavian forest mile. == Other Scandinavian miles ==

Forest mile Beyond the normal mile, there was also a "forest mile" () that was half as long as the normal '''', i.e. a bit over , and equal to an even older unit of measurement, the ('rest', 'pause'), so named since it was seen as the distance a man would normally be able to walk between rests, equivalent to approximately four modern nautical miles or "medium meridian minutes" (4 × 1,852 m) – a nautical mile is approximately one sixtieth of a degree along a meridian (1/60 meridian degree). During metrification in 1875, this brought it down to about from its former equivalence of 3950 fathoms (, ) or about . When the international nautical mile was introduced in Norway 1929 the sjømil was then declared a synonym for 1 NM, but informally it has since often been a reference to similar to the former distance. In Sweden, the international nautical mile is often referred to as , were as the older can refer to either the old and the new in terms of context. In Finnish, meripeninkulma, was redefined as 1 NM. == In literature ==

Naomi Mitchison, in her autobiographic book You May Well Ask, relates an experience during a walking tour in Sweden: "Over in Gotland I walked again, further than I would have if I had realized that the milestones were in old Swedish miles, so that my disappointing three-mile walk along the cold sea edge under the strange ancient fortifications was really fifteen English miles". == See also ==
