The klafter is an historical unit of length, volume and area that was used in Central Europe.
Unit of lengthedit
As a unit of length, the klafter was derived from the span of a man's outstretched arms and was traditionally about 1.80 metres (m). In Austria, its length was, for example, 1.8965 m, in Prussia 1.88 m. In Bavaria, however, a klafter was only 1.751155 m, in Hesse it was significantly larger at 2.50 m. The Viennese or Lower Austrian klafter was fixed by Rudolf II as a measure of length as of 19 August 1588.[1] When, in 1835, the Swiss units were defined using the metric system, 1 Swiss klafter (of 6 Swiss feet each of 0.30 m) corresponded exactly to 1.80 m.
The survey of Austria-Hungary began in 1762 with the construction of the Vienna Neustadt Baseline (Wiener Neustädter Grundlinie) which was 6,410, later 5,000, klafters long, represented by 5 measuring rods of 1 klafter in length made of varnished wood.
Unit of volumeedit
The old unit of dry volume for split firewood, or Scheitholz, was based on this unit of length. A klafter of wood corresponded to a stack of wood with a length and height of one klafter; the depth of this pile corresponded to the length of the log but, as a rule was 3 feet long, that is 0.5 klafters. The volume of a pile of logs was therefore only 0.5 cubic klafters. This in turn corresponded, depending on the area, to 3 to 4 steres or approximately 2 to 3 m³ of wood. The old Prussian klafter corresponded to 3.339 m³; in Austria, a klafter was equivalent to 3.386 m³.[3] By comparison the North American cord, used to measure firewood and pulpwood, is slightly larger at 3.62 m³.[4]
In Switzerland, Werdenfelser Land and parts of Lower Franconia, a klafter of logs corresponds to 3.0 m³ (steres) of stacked firewood since the introduction of the metric system. Usually the logs are 1 m long. One klafter of firewood is thus equivalent to about 2.2 m³.
Hay was also sometimes measured in klafters in the 19th century.[5]
The cubic klafter was not standardised as the length of a foot varied depending on the region. The cubic klafter used for wood could also differ. Here is an example of the Austrian units.[6]
The Rahmklafter,[7] as the unit of timber measurement was called in Austria, was defined for long and short firewood as follows:
1 Rahmklafterof long firewood = 6 feet long and 6 feet high, 1 1/4 ells of log length, about 111 cubic feet
1 Rahmklafterof short firewood = 6 feet long and 6 feet high, 1 ell of log length, about 90 cubic feet
Two klafters were counted for one Stoß or livestock unit.
Unit of areaedit
In Austria, 1 yoke (Joch, with which the size of fields was measured) comprised 1,600 square klafters with sides measuring 8 by 200 klafters, thus about 5,754 m2 and 0.575 ha, respectively. 1 square klafter (Viennese) was equivalent to 3.5979 square metres.[8]
In Croatia, the square klafter was used as unit of area and equalled 3.596652 m2. It is sometimes still used today.[9]
In the adjoining Principality of Liechtenstein, the square klafter is still used today for the measurement of land areas. 1 m2 equals 0.27804 square klafters, 1 square klafter equals 3.59665 m2. The klafter as a unit of length was consequently about 1.8965 metres long.
