How to Convert Fermi to X-Unit
1 F, f = 0.00997924317419767 X
Example: convert 15 F, f to X:
15 F, f = 15 × 0.00997924317419767 X = 0.149688647612965 X
Fermi to X-Unit Conversion Table
| fermi | X-unit |

Fermi
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.
X-Unit
An X-unit is a unit of length approximately equal to 1.002 x 10⁻¹³ meters.
History/Origin
The X-unit was proposed by the Swedish physicist Manne Siegbahn in 1919 for measuring the wavelengths of X-rays and gamma rays.
Current Use
The X-unit has been largely replaced by the angstrom and the picometer.
