Convert Earth's equatorial radius to millimeter
Please provide values below to convert Earth's equatorial radius [R_e] to millimeter [mm], or Convert millimeter to Earth's equatorial radius.
1 R_e = 6378137000 mm. To convert Earth's equatorial radius to millimeter, multiply the value by 6378137000; to go the other way, divide by it (1 mm = 1.5679e-10 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
- 1 R_e = 6378137000 mm
- 1 mm = 1.5679e-10 R_e
- 10 R_e = 63781370000 mm

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.
Millimeter
A millimeter is a unit of length in the metric system, equal to one-thousandth of a meter.
History/Origin
The prefix "milli-" comes from the Latin word "mille," meaning thousand. The millimeter was part of the original metric system adopted in France in 1795.
Current Use
The millimeter is widely used in engineering and manufacturing for high-precision measurements. It is also a common unit in construction and for measuring small objects.
