Convert full A to kilometers: an A = 1 × 1.0E-13 = 1.0E-13 kilometers.

Convert two A to kilometers: two A = 2 × 1.0E-13 = 2.0E-13 kilometers.

Convert five As to kilometers: 5 angstroms = 5 × 1.0E-13 = 5.0E-13 kilometers.

More Examples:

Convert ten As to kilometers: 10 angstroms = 10 × 1.0E-13 = 1.0E-12 kilometers.

Convert twenty As to kilometers: 20 angstroms = 20 × 1.0E-13 = 2.0E-12 kilometers.

Convert fifty As to kilometers: 50 angstroms = 50 × 1.0E-13 = 5.0E-12 kilometers.

Convert a hundred As to kilometers: 100 angstroms = 100 × 1.0E-13 = 1.0E-11 kilometers.

Convert a thousand As to kilometers: 1000 angstroms = 1000 × 1.0E-13 = 1.0E-10 kilometers.

Definition of Angstrom

The ångström (A) is a unit of length equal to 10⁻¹⁰ m or 0.1 nm. Its symbol is the Swedish letter Å. The ångström is used in the natural sciences and technology to express very small sizes comparing to that of atoms, and molecules. The ångström is not formally a part of the the International System of Units (SI) and its use is officially discouraged in SI. The closest SI unit, the nanometer (10⁻⁹ m), is recommended for use instead of ångström.

Definition of Kilometer

A kilometer (km) is a decimal multiple of the meter, the International System of Units (SI) unit of length, approximately equivalent to 39.37 inches. A kilometer is now used officially for expressing distances between geographical places on land in most of the world with notable exceptions being the United States and the United Kingdom.
