Convert Earth's polar radius to mile
Please provide values below to convert Earth's polar radius [R_p] to mile [mi, mi(Int)], or Convert mile to Earth's polar radius.
1 R_p = 3949.90275541 mi, mi(Int). To convert Earth's polar radius to mile, multiply the value by 3949.90275541; to go the other way, divide by it (1 mi, mi(Int) = 0.000253170789744 R_p). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
Mile
A mile is a unit of length in the imperial and US customary systems of measurement. The international mile is defined as exactly 1,609.344 meters.
History/Origin
The word "mile" comes from the Latin "mille passus," meaning "a thousand paces." The Roman mile spread throughout their empire. The English statute mile was established by an Act of Parliament in 1592.
Current Use
The mile is used for measuring distances on roads in the United States and the United Kingdom. It is also used in horse racing.
