Please provide values below to convert Earth's distance from sun [AU_dist] to femtometer [fm], or Convert femtometer to Earth's distance from sun.
How to Convert Earth's Distance From Sun to Femtometer
1 AU_dist = 1.495978707e+26 fm
Example: convert 15 AU_dist to fm:
15 AU_dist = 15 × 1.495978707e+26 fm = 2.2439680605e+27 fm

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.
Femtometer
A femtometer is a unit of length in the metric system equal to 10^-15 meters. It is also known as a fermi.
History/Origin
The prefix "femto-" for 10^-15 was adopted by the CGPM (General Conference on Weights and Measures) in 1964. The unit is also named after the physicist Enrico Fermi.
Current Use
The femtometer is primarily used in nuclear physics to measure the size of atomic nuclei.
