The Klafter is a historical unit of length originating from Central Europe, particularly prominent in German-speaking regions like Austria, Bavaria, Prussia, and Switzerland. It is conceptually similar to the fathom, often defined by the span of a person's outstretched arms.
While its exact length varied significantly by region and time, a widely recognized standard, especially from the Austrian Empire, defines the Klafter as 6 Vienna feet (Wiener Fuß). This equates to approximately:
- 1.8965 meters (m)
- 6.222 feet (ft) (using the Vienna foot of ~0.31608 m)
The Klafter was also used as a unit of area (Quadratklafter or square Klafter) and volume (Kubikklafter or cubic Klafter), especially for measuring firewood (often called a Raummeter or Ster in this context, though volumes could vary). This page focuses on the linear Klafter.
The millimeter (symbol: mm) is a unit of length in the metric system equal to one-thousandth of a meter (1/1,000 m) or one-tenth of a centimeter (1/10 cm). It is used for precise measurements in engineering, manufacturing, and everyday applications.
Key relationships:
- 1 millimeter = 0.001 meters (m)
- 1 millimeter = 0.1 centimeters (cm)
- 10 millimeters = 1 centimeter
- 1,000 millimeters = 1 meter
- 1 millimeter ≈ 0.03937 inches (about 1/25th inch)
- 25.4 millimeters = 1 inch (exactly)
The prefix "milli-":
- From Latin "mille" meaning "thousand"
- SI prefix denoting 10⁻³ (one-thousandth)
- Also used in: milligram (mg), milliliter (mL), millisecond (ms)
Visual perspective (how big is it?):
- 1 mm = Thickness of a credit card
- 2 mm = Thickness of a US dime
- 5 mm = Thickness of a pencil lead (mechanical)
- 10 mm = Width of an adult fingernail
- 25.4 mm = Exactly one inch

Note: The Klafter is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Millimeter belongs to the metric (SI) system.
History of the Klafter and Millimeter
The term "Klafter" likely derives from Old High German klāftra, related to the act of embracing or grasping, reflecting its origin as an anthropometric unit based on arm span.
- Regional Variations: Before widespread standardization and metrication, the length of the Klafter differed across various German states and Swiss cantons. For example, the Prussian Klafter was slightly different from the Austrian one.
- Standardization Efforts: Attempts were made to standardize measures, with the Austrian system (based on the Wiener Fuß) becoming influential. The definition of 1 Klafter = 6 Fuß (feet) = 72 Zoll (inches) was common, but the length of the Fuß itself varied.
- Dual Use (Length & Volume): The Klafter was notably used for measuring stacked firewood. A Klafter Holz typically referred to a stack of wood 1 Klafter high, 1 Klafter wide, and a specific log length (often 3 or 4 feet), representing a volume unit.
- Metrication: The Klafter became obsolete following the adoption of the metric system across Central Europe, primarily during the latter half of the 19th century (e.g., Germany 1872, Austria 1876).
-
Metric System Origins: The millimeter was defined as a subunit of the meter when the metric system was established in France during the late 18th century (1790s). As measurement standardization progressed, the need for decimal subdivisions of the meter became clear.
-
Industrial Revolution: The millimeter became essential during the 19th century Industrial Revolution as:
- Precision machining required fine tolerances
- Interchangeable parts manufacturing emerged
- Engineering drawings needed standard units
- Technical specifications became international
-
Engineering Adoption: By the mid-19th century, engineers and machinists worldwide adopted millimeters as the standard for:
- Machine tool specifications
- Tolerance requirements (±0.1 mm common)
- Technical drawing dimensions
- Quality control measurements
-
Scientific Standardization: The millimeter became standard in scientific research for:
- Laboratory equipment calibration
- Microscopy measurements
- Specimen documentation
- Experimental apparatus dimensions
-
SI Formalization: When the International System of Units (SI) was established in 1960, the millimeter was confirmed as an official subdivision of the meter, forming part of the coherent decimal system.
-
Modern Manufacturing: The 20th century saw millimeters become universal in:
- Automotive engineering specifications
- Electronics manufacturing (PCB design)
- Aerospace tolerances
- Medical device specifications
- Consumer product dimensions
-
Global Standard: Today, millimeters are the primary unit for precision measurements in virtually every country except the United States (which uses both mm and inches). Even in the US, many technical fields have adopted millimeters as standard.

What were the main related units in the Austrian system?
The Klafter was part of a system:
- 1 Klafter = 6 Fuß (Vienna Foot or Wiener Schuh)
- 1 Fuß = 12 Zoll (Vienna Inch or Wiener Zoll)
- 1 Zoll ≈ 2.634 cm / 1.037 inches
- 1 Fuß ≈ 31.608 cm / 12.444 inches / 1.037 feet
Where was the Klafter primarily used?
It was used across Central Europe, notably in:
- Austria-Hungary
- Southern German states (Bavaria, Württemberg)
- Prussia (with a slightly different length)
- Switzerland
- Other parts of the Holy Roman Empire and subsequent German Confederation.
Is the Klafter still used today?
No, the Klafter is obsolete for practical measurements. It was replaced by the meter during metrication in the 19th century. Its relevance is purely historical.
How does a Klafter compare to a meter or foot?
- A Klafter (~1.9 m) is almost twice as long as a meter. (1 Klafter ≈ 1.9 m)
- A Klafter (~6.2 ft) is significantly longer than a standard foot. (1 Klafter ≈ 6.2 ft)
Is the Klafter an SI unit?
No, the Klafter is not an SI unit. It is a traditional unit from historical Central European measurement systems. The SI base unit for length is the meter (m).
