What is a Parsec and a Klafter?
The Parsec (symbol pc) is a unit of length used to measure the enormous distances to astronomical objects outside the Solar System. One parsec is defined as the distance at which one astronomical unit (AU) – the average distance between the Earth and the Sun – subtends an angle of one arcsecond (1/3600th of a degree). This corresponds to approximately:
- 3.0857 × 10¹⁶ meters (m)
- 30.857 trillion kilometers (km)
- 19.174 trillion miles (mi)
- 206,264.8 astronomical units (AU)
- 3.26156 light-years (ly)
It is derived directly from the method of trigonometric parallax used by astronomers to measure stellar distances.
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.
Note: The Parsec is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Klafter belongs to the imperial/US customary system.
History of the Parsec and Klafter
The concept of measuring stellar distances via parallax existed long before the unit itself. The term "parsec" was coined by the British astronomer Herbert Hall Turner in 1913. He sought a convenient unit for astronomers that directly reflected the observational method. The name is a portmanteau derived from "parallax of one arcsecond". It quickly gained acceptance within the astronomical community due to its practical connection to parallax measurements, which were (and still are) a fundamental way to determine distances to nearby stars.
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).
Common Uses for parsecs and klafter
Explore the typical applications for both Parsec (imperial/US) and Klafter (imperial/US) to understand their common contexts.
Common Uses for parsecs
The parsec is the preferred unit of distance in professional astronomy and astrophysics:
- Stellar Distances: Measuring distances to nearby stars using parallax.
- Galactic Structure: Describing distances within the Milky Way galaxy (often using kiloparsecs, kpc, where 1 kpc = 1000 pc). For example, the Sun is about 8 kpc from the Galactic Center.
- Extragalactic Distances: Measuring distances to other galaxies and galaxy clusters (often using megaparsecs, Mpc, where 1 Mpc = 1,000,000 pc). The Hubble constant, describing the expansion of the universe, is typically expressed in (km/s)/Mpc.
- Cosmology: Discussing large-scale structures and distances in the universe (using Mpc and sometimes gigaparsecs, Gpc, where 1 Gpc = 1000 Mpc).
Common Uses for klafter
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.
Frequently Asked Questions
Questions About Parsec (pc)
What does 'Parsec' stand for?
Parsec is a blend of "parallax of one arcsecond". It represents the distance at which the parallax angle of a star is exactly one second of arc.
How is a parsec defined?
It's defined based on trigonometry. Imagine a right-angled triangle in space where the short side is the Earth-Sun distance (1 AU). The parsec is the length of the adjacent side when the angle at the distant star (the parallax angle) is exactly one arcsecond.
Is a Parsec bigger than a Light Year?
Yes, one parsec is significantly larger than one light-year.
- 1 Parsec ≈ 3.26 light-years
How many meters or kilometers are in a parsec?
One parsec is approximately:
- 3.0857 × 10¹⁶ meters
- 30.857 trillion kilometers
How many Astronomical Units (AU) are in a parsec?
One parsec is equal to approximately 206,265 AU. This number arises directly from the definition involving radians and arcseconds (specifically, the number of arcseconds in a radian).
Why do astronomers use parsecs instead of light-years?
While both are used, parsecs are often preferred in professional contexts because:
- Direct Observational Link: The parsec is derived directly from the parallax angle, a primary method for measuring distance.
- Historical Convention: It became the standard unit early in the development of stellar distance measurement.
- Convenience: Multiples like kpc and Mpc provide convenient scales for galactic and extragalactic distances.
- Definition Stability: The definition of a light-year depends slightly on the definition of a "year" (e.g., Julian year), whereas the parsec is based on the fixed AU and geometric angles.
Is the parsec an SI unit?
No, the parsec is not an SI unit. The SI unit for length is the meter (m). However, the parsec (along with the astronomical unit and light-year) is recognized by the International Astronomical Union (IAU) and is widely accepted for use in astronomy.
About Klafter (klafter)
How long is a Klafter?
The length varied, but the most common standard, based on the Austrian system, is:
- Exactly 6 Vienna Feet (Wiener Fuß)
- Approximately 1.8965 meters
- Approximately 6.222 feet
Other historical values might range roughly from 1.7 to 1.95 meters depending on the specific regional "foot" standard used.
Is a Klafter the same as a fathom?
Conceptually, they are very similar, both derived from the span of outstretched arms. Numerically, they are close but distinct.
- Klafter (Austrian): ~1.8965 meters / ~6.222 feet
- Fathom (International): Exactly 1.8288 meters / 6 feet
So, the common Austrian Klafter was slightly longer than the standard fathom.
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).
