Convert petameter to Earth's equatorial radius
Enter a value below to convert petameter [Pm] to Earth's equatorial radius [R_e]. Reverse conversion: 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: Definition and Use
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: Definition and Use
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.
