Convert petameter to Earth's equatorial radius
Please provide values below to convert petameter [Pm] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to petameter.
1 Pm = 156785594.289 R_e. To convert petameter to Earth's equatorial radius, multiply the value by 156785594.289; to go the other way, divide by it (1 R_e = 6.378137e-09 Pm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Petameter
A petameter is a unit of length in the metric system equal to 10^15 meters.
History/Origin
The prefix "peta-" for 10^15 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The petameter is used for measuring distances on a galactic scale, such as the size of the Milky Way galaxy.
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.
