Meter to Klafter Conversion Calculator: Free Online Tool

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 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).

Historically, the Klafter served various measurement needs:

• Forestry: Measuring timber lengths and, crucially, the volume of stacked firewood.
• Mining: Measuring the depth of shafts and the length of tunnels.
• Construction: Measuring building dimensions, rope lengths, and materials.
• Surveying: Measuring land distances and areas (Quadratklafter), although units like the Ruthe (rod) were also common for land.
• Nautical: Sometimes used similarly to a fathom for measuring water depth or rope lengths, though less common than the English fathom in maritime contexts.

Today, its use is confined to historical records, architectural studies, forestry history, and understanding old land deeds or documents.
