Convert fermi to Earth's equatorial radius
Enter a value below to convert fermi [F, f] to Earth's equatorial radius [R_e]. Reverse conversion: Convert Earth's equatorial radius to fermi.
1 F, f = 1.5679e-22 R_e. To convert fermi to Earth's equatorial radius, multiply the value by 1.5679e-22; to go the other way, divide by it (1 R_e = 6.3781e+21 F, f). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Fermi: Definition and Use
A fermi is a unit of length equal to a femtometer, which is 10⁻¹⁵ meters.
History/Origin
The fermi is named after the Italian-American physicist Enrico Fermi. It was a popular unit in nuclear physics.
Current Use
The femtometer is the officially recognized SI unit, but the fermi is still used informally in nuclear and particle physics.
Earth's Equatorial Radius: Definition and Use
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.
Fermi to Earth's Equatorial Radius: Frequently Asked Questions
What is 1 fermi in Earth's equatorial radius?
1 fermi (F, f) = 1.5679e-22 Earth's equatorial radius (R_e).
How do you convert fermi to Earth's equatorial radius?
Multiply the fermi value by 1.5679e-22. For example, 25 F, f × 1.5679e-22 = 3.9196e-21 R_e.
