Chains to Nanometers Conversion
Converting Chains (ch) to Nanometers (nm) is a common length conversion. 1 ch equals 20,116,800,000 nm. For example, 100 ch is equal to 2,011,680,000,000 nm.

Reference a linear anchor between chains and nanometers; use one memorable value.
Why is converting Chains to Nanometers tricky?
Magnitude or direction confusion between chains and nanometers is the primary error source.
Quick Reference Values
1 ch = 20,116,800,000 nm. 5 ch = 100,584,000,000 nm. 10 ch = 201,168,000,000 nm. 25 ch = 502,920,000,000 nm. 50 ch = 1,005,840,000,000 nm. 100 ch = 2,011,680,000,000 nm.
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 Nanometers?
Nanometers (nm) is a unit of length. The nanometer is a unit of length equal to one billionth of a meter (10⁻⁹ m). It measures dimensions at the atomic and molecular scale and is defined precisely within the International System of Units (SI). Nanometers are essential in fields such as optics, semiconductor manufacturing, and nanotechnology [bipm-si-brochure]. The nanometer was introduced during the 20th century with advances in microscopy and quantum physics. It became standardized as an SI submultiple to measure extremely small lengths for scientific and industrial applications [bipm-si-brochure]. Nanometers are used globally in semiconductor fabrication, optics, and material science. Industries such as computer chip manufacturing specify process nodes in nanometers, reflecting international standards [nist-cuu].
Common Misspellings
People often search for this conversion using these alternate spellings: chaines, chian, chainz, chaine, nanometer, nanometre, nanomiter, nanomiter. All of these refer to the Chains to Nanometers conversion.
