Context values
Some unit families need one extra value for a physically accurate result.
An angstrom is 1e-10 meters.
Result = input x 0.201168 / 1e-10.
Length uses the meter as the base unit.

About Converting Links to Angstroms
Link and Angstrom both measure length. Specifically: A surveyor's link is 1/100 of a chain, and an angstrom is 1e-10 meters.
Formula
angstroms = links × 2011680000
This factor comes from each unit's defined relationship to the category's base unit: 1 link equals 0.201168 base units, and 1 angstrom equals 1e-10 base units, so dividing one by the other gives the direct link-to-angstrom factor of 2011680000.
Simple example
1 li × 2011680000 = 2,011,680,000 A
1 link = 2,011,680,000 angstroms.
Real-world example
10 li × 2011680000 = 20,116,800,000 A
10 links = 20,116,800,000 angstroms.

Reverse conversion: Angstrom to Link
1 A × 4.97097e-10 = 4.97097e-10 li
1 angstrom = 4.97097e-10 links.
links = angstroms × 4.97097e-10

Understanding the Link (li)
A surveyor's link is 1/100 of a chain.
Understanding the Angstrom
Angstrom (A) measures length. Equal to exactly 10⁻¹⁰ meters (0.1 nanometers) — a scale convenient for describing atomic radii, bond lengths, and crystal structures. It is classified as a non-SI unit, still common in chemistry and crystallography.
Where it's used: Widely used internationally in chemistry, crystallography, and atomic/molecular physics
Uses of the Angstrom today
- Atomic and ionic radii in chemistry
- Chemical bond-length measurements
- X-ray crystallography and wavelength measurements
History of the Angstrom
The angstrom is named after Anders Jonas Ångström (1814–1874), a Swedish physicist and one of the founders of spectroscopy, who used the unit in his 1868 atlas of the solar spectrum.
Historical origin. Angstrom was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many angstroms are in 1 link?
1 link equals 2,011,680,000 angstroms, using the exact defined conversion factor rather than an estimate.
How do I convert link to angstrom?
Multiply the link value by 2011680000. The converter above does this instantly to whatever precision you set.
How do I convert angstrom back to link?
Use the reverse factor: 1 angstrom equals 4.97097e-10 links. You can also use the swap control in the converter above to flip the direction instantly.
What is a link?
Link (li) is a unit of length.
What is a angstrom?
Angstrom (A) measures length. Equal to exactly 10⁻¹⁰ meters (0.1 nanometers) — a scale convenient for describing atomic radii, bond lengths, and crystal structures. It is classified as a non-SI unit, still common in chemistry and crystallography.
Is the link to angstrom conversion exact?
Yes. Equal to exactly 10⁻¹⁰ meters (0.1 nanometers) — a scale convenient for describing atomic radii, bond lengths, and crystal structures. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
