Convert mil to Earth's equatorial radius
Please provide values below to convert mil [mil, thou] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to mil.
1 mil, thou = 3.9824e-12 R_e. To convert mil to Earth's equatorial radius, multiply the value by 3.9824e-12; to go the other way, divide by it (1 R_e = 251107755906 mil, thou). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mil, thou = 3.9824e-12 R_e
- 1 R_e = 251107755906 mil, thou
- 10 mil, thou = 3.9824e-11 R_e
- 100 mil, thou = 3.9824e-10 R_e
How to Convert Mil to Earth's Equatorial Radius
1 mil, thou = 3.98235409493399e-12 R_e
Example: convert 15 mil, thou to R_e:
15 mil, thou = 15 × 3.98235409493399e-12 R_e = 5.97353114240099e-11 R_e

Mil
A mil, also known as a thou, is a unit of length equal to one-thousandth of an inch.
History/Origin
The mil was introduced in the 19th century as a convenient unit for fine measurements in engineering and manufacturing.
Current Use
The mil is still used in some manufacturing and engineering contexts, particularly in the United States, for specifying the thickness of materials like paper and wire.
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.
Frequently Asked Questions
What is 1 mil in Earth's equatorial radius?
1 mil (mil, thou) = 3.9824e-12 Earth's equatorial radius (R_e).
