Angstrom (Å)
Length
Traceable to the metre, defined by fixing the speed of light in vacuum at 299 792 458 m/s. Imperial lengths derive from the 1959 international yard (0.9144 m exactly).

How to Convert Angstrom to Kilometer
To convert from Angstrom (Å) to Kilometer (km), multiply the value by 1.000000e-13.
Formula: km = Å × 1.000000e-13
Reverse: Å = km × 1.000000e+13
Step-by-Step Example
- Start with your value in Angstrom. For example: 5 Å
- Multiply by the conversion factor: 5 x 1.000000e-13
- The result is: 5.000000e-13 km
About Angstrom
The angstrom (Å) equals 10⁻¹⁰ metres, or 0.1 nanometres — roughly the diameter of a hydrogen atom, which is why it survives in crystallography and spectroscopy.
Common uses: crystallography, atomic physics, semiconductors.
About Kilometer
The kilometer equals 1,000 meters and is the standard unit for measuring distances between geographical locations in most countries.
Fun Fact: The circumference of Earth is approximately 40,075 km.
Common uses: road distances, geography, running.
