Meters to Astronomical Units

Meter

A meter (m) is the base unit of length in the metric system and one of the most widely used measurements in the world. It is defined precisely by the distance light travels in a vacuum during a fraction of a second, making it highly accurate for scientific use. In everyday life, meters measure things like room dimensions, athletic tracks, and object heights.

Because the meter anchors the entire metric system, converting to centimeters, kilometers, or millimeters is simple and consistent. Unit converters make switching between systems—such as meters and feet—fast and reliable for any project.

Astronomical Unit

An astronomical unit (AU) is a standard space measurement based on the distance from the Earth to the Sun—about 149.6 million kilometers or 93 million miles. It helps describe solar system distances in practical numbers rather than extremely large values.

Astronomers use AU values to measure orbits of planets, asteroids, and comets relative to Earth.
