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.
Megameters
A megameter (Mm) is a unit of length in the International System of Units (SI). One megameter is equivalent to 1,000,000 meters or approximately 621.371 miles.
The megameter is defined as one million meters, providing a measurement for very large distances, such as those encountered in planetary and astronomical contexts.
Megameters are used in fields such as astronomy and planetary science to describe distances on a scale larger than kilometers but smaller than astronomical units.
