# Icelandic units of measurement

A number of units of measurement were used in Iceland to measure length, mass, area, capacity, etc. Since 1907, metric system has been compulsory in Iceland.^{[1]}^{[2]}

## Older System of Unit before Metric System

A number of units were used and these units were analogues to Danish.

### Length

A number of units were used in Iceland to measure length. One fet was equal to 0.31385 m and one sjómíla was equal to 1855 m, as they were defined by their metric equivalents.^{[1]} Some other units are given below:^{[1]}^{[3]}

1 lína = 1/144 fet

1 þumlungur = 1/12 fet

1 alin = 2 fet

1 faðmur = 6 fet

1 míla á landi (or landmíla) = 24,000 fet

Þingmannaleið = 20,000 faðmar = 120,000 fet^{[4]}

### Mass

A number of units were used to measure mass. One pund was equal to 0.5 kg as it was defined by its metric equivalent.^{[1]} Some other units are given below:^{[1]}^{[3]}

1 mörk = 1/2 pund^{[5]}

1 fisk = 8 pund

1 fierding = 40 pund

1 liespund = 64 pund

1 tunna smjörs = 224 pund

1 skippund = 320 pund

1 batt = 320 pund

## Area

A number of units were used to measure area. One ferfaðmur (plural. ferfaðmar) was equal to 3.546 m^{2} and one fermila was equal to 56.7383 km^{2}, as they were defined by their metric equivalents.^{[1]} Some other units are given below:^{[1]}

1 ferþumlungur = 1/5184 ferfaðmur

1 ferfet = 1/36 ferfaðmur

1 feralin = 1/9 ferfaðmur

1 túndagslátta = 900 ferfaðmar

1 engjateigur = 1600 ferfaðmar

### Capacity

A number of units were used to measure capacity. One pottur (plural. pottar) was equal to 1/32 fet^{2}, and was equal to 0.9661 l as it was defined by its metric equivalent.^{[1]} Some other units are given below:^{[1]}^{[3]}

1 kornskeppa = 18 pottar

1 anker = 39 pottar

1 almenn tunna = 120 pottar

1 öltunna = 136 pottar

1 korntunna = 144 pottar
