Swedish units of measurement

In Sweden, a common system for weights and measures was introduced by law in 1665. Before that, there were a number of local variants. The system was slightly revised in 1735. In 1855, a decimal reform was instituted that defined a new Swedish inch as  ¹⁄₁₀ Swedish foot (2.96 cm or 1.17 inches). Up to the middle of the 19th century, there was a law allowing for the imposition of the death penalty for falsifying weights or measures. Sweden adopted the metric system in 1889. Only the Swedish mile, mil, has been preserved, now measuring 10 kilometres (6.2 statute miles).

Length

The Swedish units of length included the following:

• aln – Forearm (cf. Ell) (pl. alnar). After 1863, 59.37 cm (1.948 ft). Before that, from 1605, 59.38 cm as defined by King Carl IX of Sweden in Norrköping 1604, based on Rydaholmsalnen.
• famn – Fathom, 3 alnar.
• kvarter – Quarter,  ¹⁄₄ aln
• fot – Foot, 1/2 aln. Before 1863, the Stockholm fot was the commonly accepted unit, at 29.69 cm (0.974 ft).
• linje – Line, after 1863  ¹⁄₁₀ tum, 2.96 mm (0.117 inches). Before that,  ¹⁄₁₂ tum or 2.06 mm.
• mil – Mile, also lantmil. From 1699, defined as a unity mile of 18000 alnar or 10.69 km (6.64 mi). The unified mile was meant to define the suitable distance between inns. (The current Swedish mil is exactly 10 kilometers.)
• nymil – New mile from 1889, 10 km exactly. Commonly used to this day, only referred to as mil.
• kyndemil – The distance a torch will last, approx 16 km (9.9 mi).
• skogsmil – Also rast, distance between rests in the woods, approx. 5 km (3.1 mi).
• fjärdingsväg –  ¹⁄₄ mil
• stenkast – Stone's throw, about 50 m (164 ft), used to this day as an approximate measure.
• rev – 160 fot, for land measurement, was 100 fot after 1855.
• stång – 16 fot, for land measurement
• tum – Thumb (inch),  ¹⁄₁₂ fot, 2.474 cm. After 1863  ¹⁄₁₀ fot, 2.96 cm, not much accepted by professional users in mechanics and carpentry who later switched to English inch (2.54 cm, abandoned only late 20th century) and metric system.
• tvärhand – Hand, 4 inches.

Area

• kannaland – 1000 fot², or 88.15 m² (948.8 sq ft)
• kappland – 154.3 m² (1,661 sq ft).
• spannland – 16 kappland
• tunnland – 2 spannland or 4,937.6 m² (53,148 sq ft), about 1 acre
• kvadratmil – Square mil, 36 million square favnar, from 1739.
