Convert Earth's polar radius to meter
Please provide values below to convert Earth's polar radius [R_p] to meter [m], or Convert meter to Earth's polar radius.
1 R_p = 6356752.3 m. To convert Earth's polar radius to meter, multiply the value by 6356752.3; to go the other way, divide by it (1 m = 1.57313035463e-07 R_p). 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 Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
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.
