A 'mil' (
Norwegian and
Swedish for
mile) is a
unit of
length, usually used to measure geographic distance, fairly common in
Norway and
Sweden. Today, it measures by definition 10 kilometres, but earlier in history it had different values.
History
In Norway and Sweden, the old "land mile" or "long mile" was 36,000 feet: because of the different definitions of foot then in use, in Norway this was 11.295 km and in Sweden 10.688 km. (Had the Imperial foot been used, the distance would have worked out to 10.9728 km.) The distance was equal to an older unit of measurement, the "rast" ("rest, pause"), representing a suitable distance between rests when walking.

When the
Metric system was introduced in Norway and Sweden in
1889 (the actual law having been passed in
1875), the ''mil'' was redefined to be exactly 10 km.
Usage
The mil is currently never used on
road signs (kilometre is the standard for all formal written distances), but almost always in informal and imprecise situations involving distances greater than several kilometres, such as "There are about 60 ''mil'' between
Trondheim and
Oslo". It is also used commonly for measuring vehicle fuel consumption ("litre per ''mil''").
