Understand Astronomical Unit and Kilometer Units
An Astronomical Unit (AU) is a unit of length, roughly the average distance between Earth and the Sun. It is approximately 149.6 million kilometers (km).
A Kilometer (km) is a unit of length in the metric system, equal to one thousand meters. To convert from Astronomical Units to kilometers, you would multiply the number of AUs by approximately 149.6 million.
How to Convert Astronomical Unit to Kilometer
- First, remember the conversion factor: 1 Astronomical Unit (AU) is approximately equal to 149.6 million kilometers.
- Next, multiply the number of AUs you have by 149,600,000.
- The result will be the equivalent distance in kilometers.
For example, if you want to convert 2 AU to kilometers, you would multiply 2 by 149,600,000, which equals 299,200,000 kilometers.
