Convert Earth's distance from sun to astronomical unit
Enter a value below to convert Earth's distance from sun [AU_dist] to astronomical unit [AU, UA]. Reverse conversion: Convert astronomical unit to Earth's distance from sun.
1 AU_dist = 1 AU, UA. To convert Earth's distance from sun to astronomical unit, multiply the value by 1; to go the other way, divide by it (1 AU, UA = 1 AU_dist). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Earth's Distance From Sun to Astronomical Unit: Quick Reference
- 1 AU_dist = 1 AU, UA
- 1 AU, UA = 1 AU_dist
- 10 AU_dist = 10 AU, UA
- 100 AU_dist = 100 AU, UA
How to Convert Earth's Distance From Sun to Astronomical Unit
1 AU_dist = 1 AU, UA
Example: convert 15 AU_dist to AU, UA:
15 AU_dist = 15 × 1 AU, UA = 15 AU, UA

Earth's Distance From Sun: Definition and Use
The Earth's distance from the Sun varies throughout the year. The average distance is defined as one astronomical unit (AU), which is about 149.6 million kilometers.
History/Origin
The measurement of the Earth-Sun distance has a long history, with early estimates made by ancient Greek astronomers. Modern measurements are highly precise.
Current Use
The Earth-Sun distance is a fundamental unit in astronomy and is used to measure distances within the solar system.
Astronomical Unit: Definition and Use
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.
Earth's Distance From Sun to Astronomical Unit: Frequently Asked Questions
What is 1 Earth's distance from sun in astronomical unit?
1 Earth's distance from sun (AU_dist) = 1 astronomical unit (AU, UA).
How do you convert Earth's distance from sun to astronomical unit?
Multiply the Earth's distance from sun value by 1. For example, 25 AU_dist × 1 = 25 AU, UA.
What is 10 Earth's distance from sun in astronomical unit?
10 AU_dist = 10 AU, UA.
Which unit is larger, the Earth's distance from sun or the astronomical unit?
The astronomical unit is the larger unit: 1 AU_dist equals only 1 AU, UA.
