About these units
Kilometers
A kilometer (km) is a unit of length in the International System of Units (SI), equal to 0.6214 miles. One kilometer is one thousand meters.
The prefix "kilo-" means one thousand. A kilometer is defined by 1000 times the distance light travels in 1/299,792,458 seconds. This definition may change, but a kilometer will always be one thousand meters.
Kilometers are used to measure distances on land in most countries. However, the United States and the United Kingdom still often use miles. The UK has adopted the metric system, but miles are still used on road signs.
Parsecs
A parsec (symbol: pc) is a unit of length used in astronomy. One parsec is approximately 3.26 light-years or 3.086 × 10¹³ kilometers.
The term parsec comes from "parallax of one arcsecond." It is the distance at which one astronomical unit subtends an angle of one arcsecond.
Parsecs are commonly used to measure large distances between astronomical objects outside our solar system, such as between stars or galaxies.
