Convert angstrom to kilometer
Please provide values below to convert angstrom [A] to kilometer [km], or Convert kilometer to angstrom.
1 A = 1.0000e-13 km. To convert angstrom to kilometer, multiply the value by 1.0000e-13; to go the other way, divide by it (1 km = 1.0000e+13 A). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 A = 1.0000e-13 km
- 1 km = 1.0000e+13 A
- 10 A = 1.0000e-12 km
- 100 A = 1.0000e-11 km
How to Convert Angstrom to Kilometer
1 A = 1e-13 km
Example: convert 15 A to km:
15 A = 15 × 1e-13 km = 1.5e-12 km

Angstrom
The angstrom is a unit of length equal to 10⁻¹⁰ meters. It is not an SI unit.
History/Origin
In 1868, Swedish physicist Anders Jonas Ångström created a chart of the spectrum of sunlight in which he expressed the wavelengths in multiples of one ten-millionth of a millimeter. The unit was named after him.
Current Use
The angstrom is used to express the sizes of atoms, molecules, and the wavelengths of electromagnetic radiation, particularly in the fields of chemistry, spectroscopy, and crystallography.
Kilometer
A kilometer is a unit of length in the metric system, equal to one thousand meters.
History/Origin
The term "kilometer" is derived from the Greek words "khilioi" (thousand) and "metron" (measure). The kilometer was first defined as part of the metric system in France in 1795.
Current Use
The kilometer is the most widely used unit of distance for road signs and travel distances in the world, with the notable exceptions of the United States and the United Kingdom.
Frequently Asked Questions
What is 1 angstrom in kilometer?
1 angstrom (A) = 1.0000e-13 kilometer (km).
How do you convert angstrom to kilometer?
Multiply the angstrom value by 1.0000e-13. For example, 25 A × 1.0000e-13 = 2.5000e-12 km.
What is 10 angstrom in kilometer?
10 A = 1.0000e-12 km.
Which unit is larger, the angstrom or the kilometer?
The kilometer is the larger unit: 1 A equals only 1.0000e-13 km.
