What is a Link (Gunter's) and a Angstrom?
The Link, specifically Gunter's Link (symbol li), is a unit of length historically used in surveying, particularly within the imperial and U.S. customary systems. It is defined as exactly 1/100th of a Gunter's chain.
One Gunter's link is equivalent to:
- 0.01 Gunter's chains
- 7.92 inches (in)
- 0.66 feet (ft) (exactly 2/3 of a foot)
- 0.22 yards (yd)
- 0.04 rods (also called poles or perches)
- 0.201168 meters (m) (exactly)
- 20.1168 centimeters (cm)
A Gunter's chain itself measures 66 feet, 22 yards, 4 rods, or 20.1168 meters.
The Angstrom (symbol Å) is a non-SI unit of length equal to exactly 10⁻¹⁰ meters (one ten-billionth of a meter) or 0.1 nanometers (nm). While not part of the modern International System of Units (SI), it remains widely used in various scientific fields due to its convenient scale for atomic and molecular dimensions. It provides a direct way to express sizes at the sub-nanometer level without resorting to fractions or powers of ten for nanometers.
Note: The Link (Gunter's) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Angstrom belongs to the imperial/US customary system.
History of the Link (Gunter's) and Angstrom
The link, as part of Gunter's chain, was devised by the English clergyman and mathematician Edmund Gunter around 1620. He introduced a measuring chain that was 66 feet long and divided into 100 links. This system was revolutionary for surveyors because its decimal nature (100 links per chain) simplified calculations, especially for area. Land area could be easily calculated in square chains and then converted to acres, as 10 square chains equal exactly 1 acre. Gunter's chain and its links became the standard tools for land surveying in England and later throughout the British Empire and the United States for centuries.
The Angstrom unit is named after the Swedish physicist Anders Jonas Ångström (1814–1874), one of the founders of the science of spectroscopy. Ångström used this unit in 1868 to create a chart of the wavelengths of electromagnetic radiation in sunlight, expressing them as multiples of 10⁻¹⁰ meters. This scale proved extremely convenient for expressing atomic radii, chemical bond lengths, and the wavelengths of X-rays. Although the nanometer (nm) and picometer (pm) are the preferred SI units for these scales today, the Angstrom's historical prevalence means it persists in many scientific disciplines, particularly in crystallography, atomic physics, and chemistry literature.
Common Uses for links and angstroms
Explore the typical applications for both Link (Gunter's) (imperial/US) and Angstrom (imperial/US) to understand their common contexts.
Common Uses for links
The Gunter's link is now largely obsolete but was historically significant:
- Land Surveying: It was the fundamental unit for measuring property boundaries and land parcels in English-speaking countries for over 300 years.
- Cartography: Used in creating maps and plats based on surveys.
- Land Records: Measurements in links (and chains) frequently appear in older property deeds, historical surveys, and legal descriptions of land. Understanding the link is crucial for interpreting these documents.
- Agriculture: The system was tied to the definition of the acre, a common unit of land area.
Its use declined dramatically with the adoption of the metric system and the advent of more precise surveying technologies like steel tapes, theodolites, Electronic Distance Measurement (EDM), and GPS.
Common Uses for angstroms
The Angstrom is frequently used to measure dimensions at the atomic scale:
- Atomic Radii: Expressing the size of atoms (e.g., the covalent radius of a carbon atom is about 0.77 Å).
- Chemical Bond Lengths: Measuring the distance between nuclei in molecules (e.g., the O-H bond length in water is about 0.96 Å).
- Crystallography: Describing the dimensions of crystal lattices and the spacing between atomic planes, often determined using X-ray diffraction.
- Spectroscopy: Specifying the wavelengths of X-rays and some ultraviolet light.
- Microscopy: Measuring features in electron microscopy images.
- Integrated Circuits: Sometimes used historically or informally to describe feature sizes in semiconductor manufacturing, although nanometers are now standard.
Frequently Asked Questions
Questions About Link (Gunter's) (li)
How long is a Gunter's Link?
One Gunter's Link is equal to:
- 7.92 inches
- 0.66 feet (2/3 ft)
- 0.201168 meters
- 20.1168 centimeters
How many links are in a Gunter's chain?
There are exactly 100 links in one Gunter's chain.
How long is a Gunter's Chain?
One Gunter's chain is equal to:
- 100 links
- 66 feet
- 22 yards
- 4 rods (or poles, perches)
- 1/10th of a furlong
- 1/80th of a statute mile
- 20.1168 meters
How does the link relate to the acre?
The link is directly related to the acre through the Gunter's chain. An acre is defined as 10 square chains. Since 1 chain = 100 links:
- 1 acre = 10 × (100 links)² = 10 × 10,000 square links = 100,000 square links. This decimal relationship greatly simplified area calculations for surveyors using the chain.
Is the link an SI unit?
No, the Gunter's link is not an SI unit. It is part of the traditional imperial and U.S. customary systems. The corresponding SI unit for length is the meter (m).
Is the Gunter's link still used today?
No, the Gunter's link is rarely used in modern surveying practice. Its primary relevance today is in historical contexts, particularly when interpreting old land deeds, surveys, and maps created using Gunter's system. Modern surveying relies on meters or feet, measured with advanced electronic equipment.
Why was it called a 'link'?
It was called a 'link' because Gunter's chain was literally constructed from 100 physical metal links connected by rings. Each link served as a unit of measurement.
About Angstrom (Å)
How many Angstroms are in a meter?
There are 10,000,000,000 (ten billion) Angstroms in one meter (1 m = 10¹⁰ Å). Conversely, 1 Angstrom = 10⁻¹⁰ meters.
How many Angstroms are in a nanometer?
There are exactly 10 Angstroms (Å) in one nanometer (nm). Therefore, 1 Å = 0.1 nm.
Is the Angstrom an SI unit?
No, the Angstrom is not part of the International System of Units (SI). The official SI unit for length at this scale is the nanometer (nm) (10⁻⁹ m) or the picometer (pm) (10⁻¹² m). 1 Å = 100 pm.
Why is the Angstrom still used if it's not an SI unit?
The Angstrom persists due to historical convention and its convenient size for atomic-scale measurements. Many scientific fields, like crystallography and atomic physics, developed using the Angstrom, and much historical data and literature use it. Its scale (0.1 nm) often allows for expressing atomic dimensions as numbers close to unity without decimals or exponents, which can be convenient.
What fields commonly use Angstroms?
The Angstrom remains common in:
- Crystallography: Describing crystal structures and diffraction patterns.
- Atomic Physics: Measuring atomic radii and energy level transitions.
- Chemistry: Specifying molecular bond lengths and structures.
- Spectroscopy: Particularly for X-ray wavelengths.
- Materials Science: Characterizing thin films and nanostructures.
- Structural Biology: Describing protein and nucleic acid structures.
