Convert Earth's equatorial radius to meter
Please provide values below to convert Earth's equatorial radius [R_e] to meter [m], or Convert meter to Earth's equatorial radius.
1 R_e = 6378137 m. To convert Earth's equatorial radius to meter, multiply the value by 6378137; to go the other way, divide by it (1 m = 1.56785594289e-07 R_e). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference

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.
Meter
The meter is the base unit of length in the International System of Units (SI). It is the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
History/Origin
The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the international prototype meter was established as the length of a prototype meter bar, made of an alloy of platinum and iridium. In 1960, the meter was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86.
Current Use
The meter is used worldwide in many applications such as science, engineering, and trade. The United States is one of the few countries in which the meter is not widely used in everyday life and trade.
