Please provide values below to convert attometer [am] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to attometer.
How to Convert Attometer to Earth's Equatorial Radius
1 am = 1.5678559428874e-25 R_e
Example: convert 15 am to R_e:
15 am = 15 × 1.5678559428874e-25 R_e = 2.3517839143311e-24 R_e
Attometer to Earth's Equatorial Radius Conversion Table
| attometer | Earth's equatorial radius |
|---|
Attometer
An attometer is a unit of length in the metric system equal to 10^-18 meters.
History/Origin
The prefix "atto-" for 10^-18 was adopted by the CGPM (General Conference on Weights and Measures) in 1964.
Current Use
The attometer is used in high-energy physics to describe the scales relevant to quarks and leptons.
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.
