# Historical weights and measures

Many systems of weights and measures have existed throughout history. The definitions of some of these units were often vague and inaccurate, and although the roots of many of the units were the same, the actual value of a unit differed from country to country, or epoch to epoch. That fact should not lead to a conclusion that historical units of measure were inaccurate in general. Many units were defined to a high precision, and standards of measurement were in many cases excellent. As a case in point, the Great Pyramid of Giza was built to a precision of 0.015 m over sides that are 235 meters, over four and a half thousand years ago.

### Mesopotamian system

Mesopotamia includes a number of cultures. The Sumerian number system uses a base 60 positional notation[?], and is the origin for the division of 60 for hours and angles.

#### Length

• kùš -- Cubit (Sumerian). Akkadian ammatu. The copper bar cubit of Nippur, the first known standard bar, defines the Sumerian cubit as 51.72 cm around 1950 BC. It was split in four units, each of these in 16 again. The Babylonian cubit was probably around 48 cm. For reference, the inner square of the Tower of Babel measured 120 by 120 cubits..
• foot -- Defined as 26.45 cm by Sumerian ruler Gudea of Lagash around 2575 BC, this is the oldest preserved standard of length.
• digit -- 1 / 16 foot or 1 / 30 cubit
• parasang -- Babylonian league is 5.6 km

#### Area

• sar -- Garden plot (Sumerian)
• iku -- "Plot of land enclosed by a boundary dike/canal", 100 sar. Probably 120 ·120 cubit²

#### Volume

• log -- 0.54 l
• homer -- 720 log

#### Weight and monetary

• shekal -- 8.36 g, introduced around 3000 BC
• mina -- 60 shekal

#### Time

• year -- The Sumerians used a 360 day year by 2100 BC.
• week -- The Babylonians introduced the seven day week, due to the belief that seven brought bad luck, so they did not want to work the seventh day.
• hour -- The 12 hour day and 12 hour night originates from Mesopotamia. The length of these hours changed through the year, being equally spaced over the time of light and dark, respectively.

### Vedic system

Vedic measures were first used by the Indian Vedic civilization, and are still in use today—primarily for religious purposes in Hinduism and Jainism.

### Persian system

The Persian system had influence on the Greek system, at least. The ghalva (stadion) and parasang were much used as a land measure. There are significant uncertainty, though.

#### Length

• finger -- 1 / 4 palm
• palm -- 1 / 4 foot
• zereth -- Foot, 1 / 2 cubit
• arsani -- Cubit, 52.0 up to 64.0 cm
• cane -- 2 paces, 6 cubits
• chebel -- 40 cubits
• stadion -- Forerunner to Greek and Egyptian stadion, presumably around 264 m
• parasang -- The distance a horse would walk for one hour, 250 chebel, approx. 6 km. (6.23 km in mid 19th century. In todays Iran as well as Turkey, a metric farsang of 10 km is commonly used. Forerunner for league.
• schoinos -- Origin of Greek and Egyptian measures
• mansion -- Equivalent to "stathmos", 4 parsang

#### Volume

### Arabic system

The Arabic system is based on the Persian system.

### Egyptian system

Much of the Egyptian system of measurement is based on the Persian. The Egyptian system in its turn formed the basis of the later Greek system. The Egyptians based their measurements on the Royal cubit, for which the pharaoh devised a standard (master) cut in granite. From these standards, it is clear that accuracies in measurements of at least 1/16 yeba (1 mm) were possible. Note also the cubit and remen which has a ratio that constitutes an irrational number. The Egyptian system was also noteworthy in having units for volume derived from the standard for length. While the Royal cubit is a very well defined unit, uncertainty is connected to the units for land measurement, especially when the Greek stadion and schoinos units came in use.

#### Length

• meh nesut -- Royal cubit, 52.3 cm, varied by less than 0.5 cm through the times.

• remen -- 1 / 2 double remen
• remen digit -- 1 / 20 remen
• khet -- Senus, 100 Royal cubit, also jet, hayt
• stadion -- 400 Royal cubits, 209.2 m
• parasang -- 10000 Royal cubits

• iter -- Royal river measure (pl. iteru or itrw), also atur or ater. 20000 Royal cubits, or 10.46 km. The units parasang, schoinos and ater seems to be often interchanged. The book of Herodotus clearly states the Egyptian mile as twice a Persian parasang, i.e. 20000 Royal cubits.

The Roman system of measurement was built on the Greek system, and lives on to this day in the form of the Imperial system. The Roman units were accurate and well documented. Distances may have been measured by odometers connected to carriage axles, for instance. The definition of some units changed over time, however. For the libra, quite significantly so.

### English system

Before the Roman based measurement system was introduced from 1066 onwards, there existed a Anglo-Saxon system of measure based on the units of the barleycorn and the gyrd (rod). This presumably had Germanic origins. Later development of the British system continued by defining the units by law in the Magna Carta of 1215, and issuing measurement standards from the then capital Winchester. Standards were renewed in 1496, 1588 and 1758. The last Imperial Standard Yard in bronze was made in 1845. See: Imperial system of units

#### Length

• barleycorn -- Basic Anglo Saxon unit, the length of a corn of barley. The unit survived after 1066, but now defined as 1/3 inch. Note the relation to the grain unit of weight.

### Danish system

From May 1, 1863, king Christian V of Denmark introduced an office to oversee weights and measures, a justervesen, to be led by Ole Rømer. The definition of the alen was set to 2 Rhine feet. Rømer later discovered that differeing standards for the Rhine foot existed, and in 1698 an iron Copenhagen standard was made. A pendulum definition for the foot was introduced in 1820, and changed in 1835. The metric system was introduced in 1907.

#### Length

• mil -- Danish mile. Towards the end of the 17th century, Ole Rømer connected the mile to the circumference of the earth, and defined it as 12000 alen. This definition was adopted in 1816 as the Prussian Meile. The coordinated definition from 1835 was 7.532 km. Earlier, there were many variants, the most commonplace the Sjællandsk miil of 17600 fod or 11.130 km.

### Norwegian system

Before 1541, there were no common definition for length measures in Norway, and local variants flourished. In 1541, an alen in Denmark and Norway was defined by law to be the Sjælland alen. Subsequently, the alen was defined by law as 2 Rhine feet from 1683. From 1824, the basic unit was defined as a fot being derived from astronomy as the length of a one second pendulum times 12/38 at a latitude of 45°. The metric system was introduced in 1887.

### Swedish system

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 instuted that defined a new Swedish inch as 1/10 foot. It did not last long, because the metric system was subsequently introduced in 1889. Up to the middle of the 19th century there was a death penalty for falsifying weights or measures.
