Convert astronomical unit to meter
Please provide values below to convert astronomical unit [AU, UA] to meter [m], or Convert meter to astronomical unit.
1 AU, UA = 149597870700 m. To convert astronomical unit to meter, multiply the value by 149597870700; to go the other way, divide by it (1 m = 6.6846e-12 AU, UA). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 AU, UA = 149597870700 m
- 1 m = 6.6846e-12 AU, UA
- 10 AU, UA = 1.4960e+12 m
- 100 AU, UA = 1.4960e+13 m
How to Convert Astronomical Unit to Meter

Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
Meter
The meter is the base unit of length in the International System of Units (SI). It is the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
History/Origin
The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the international prototype meter was established as the length of a prototype meter bar, made of an alloy of platinum and iridium. In 1960, the meter was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86.
Current Use
The meter is used worldwide in many applications such as science, engineering, and trade. The United States is one of the few countries in which the meter is not widely used in everyday life and trade.
