Chains to Micrometers Conversion
Converting Chains (ch) to Micrometers (µm) is a common length conversion. 1 ch equals 20,116,800 µm. For example, 100 ch is equal to 2,011,680,000 µm.
Quick Mental Math: Chains to Micrometers
Multiply chains (surveying) by 20.1M to estimate micrometers.
Why is converting Chains to Micrometers tricky?
Both units are specialized or archaic, with almost no overlap in modern use.
Quick Reference Values
1 ch = 20,116,800 µm. 5 ch = 100,584,000 µm. 10 ch = 201,168,000 µm. 25 ch = 502,920,000 µm. 50 ch = 1,005,840,000 µm. 100 ch = 2,011,680,000 µm.
What is Chains?
Chains (ch) is a unit of length. A chain is a unit of length equal to 66 feet or exactly 20.1168 meters. It was historically used in land surveying and equals 100 links. The chain is defined as 66 feet to maintain consistency with imperial measurements and is standardized for surveying purposes [nist-si-guide]. The chain was introduced by Edmund Gunter in 1620 to simplify land measurement and surveying. Adopted widely in English-speaking countries, it facilitated mapping and land division before metric units became prevalent [nist-si-guide]. Chains are primarily used in surveying and real estate in the United States, Canada, and parts of Australia. Although largely replaced by metric units globally, chains remain a legal unit in some jurisdictions for land records [nist-si-guide].
What is Micrometers?
Micrometers (µm) is a unit of length. A micrometer, symbolized as µm, equals one millionth of a meter or 10⁻⁶ meters. It is the SI derived unit for length used to measure microscopic distances and thicknesses. This precise definition aligns with the International System of Units established by the BIPM [bipm-si-brochure]. The micrometer was standardized in the 20th century following adoption of the meter as the base unit by the CGPM. Its use became widespread in scientific fields requiring fine measurement, formalized in SI documentation [cgpm-resolutions]. The micrometer sees global use in sectors like semiconductor manufacturing, biology, and materials science. Countries with advanced manufacturing industries such as Japan, Germany, and the USA standardize on µm for precise length measurements [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: chaines, chian, chainz, chaine, micronmeter, micrometeres, micomenter, micrmeters. All of these refer to the Chains to Micrometers conversion.
