Please provide values below to convert Earth's equatorial radius [R_e] to Earth's distance from sun [AU_dist], or Convert Earth's distance from sun to Earth's equatorial radius.
How to Convert Earth's Equatorial Radius to Earth's Distance From Sun
1 R_e = 4.26352124542639e-05 AU_dist
Example: convert 15 R_e to AU_dist:
15 R_e = 15 × 4.26352124542639e-05 AU_dist = 0.000639528186813959 AU_dist

Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
Earth's Distance From Sun
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.
