Lightyears A light-year is a unit of length used in astronomy to measure vast distances. One light-year is equivalent to approximately 9.461 trillion kilometers or about 5.879 trillion miles.
A light-year is defined by the distance that light travels in a vacuum in one year, which is about 9.461 × 10^12 kilometers.
Light-years are used to measure distances between stars, galaxies, and other celestial objects. They provide a convenient way to express astronomical distances, making it easier to understand the scale of the universe.
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.
