SUMMARY

The value of Fermi's constant (GF) in SI units is established as 4.54376275 × 1014 J-2. This value is derived from the relationship GF / (ℏc)3 = 1.16637 × 10-5 GeV-2. To convert GF from Joules to CGS units, one can utilize the conversion factor from Joules to ergs, where 1 Joule equals 107 ergs.

PREREQUISITES
  • Understanding of Fermi's constant (GF)
  • Knowledge of quantum mechanics concepts such as ℏ (reduced Planck's constant) and c (speed of light)
  • Familiarity with unit conversions between SI and CGS systems
  • Basic proficiency in scientific notation and calculations
NEXT STEPS
  • Research the implications of Fermi's constant in particle physics
  • Learn about the conversion process from Joules to ergs
  • Explore the significance of the constants ℏ and c in quantum field theory
  • Study the relationship between energy units in GeV and Joules
USEFUL FOR

Physicists, students studying quantum mechanics, and anyone interested in particle physics and unit conversions in scientific calculations.

what is the value of fermi's constant ( GF ) in SI units?
I tried to work it out, but it seems that I'm wrong, I got a value of: 6.5 X 10(41) J(-2)

Does it make sense?
 
Physics news on Phys.org
Google calculator gives:

<br /> G_F = 4.54376275 \times 10^{14} J^{-2}<br />

where

<br /> \frac{G_F}{(\hbar c)^3} = 1.16637 \times 10^{-5} GeV^{-2}<br />

I used the following code in Google:

Code: 
1.16637*10^-5 (GeV)^-2 in (Joules)^-2
 
so, you mean Gf / (h.bar X c) ^ 3 = 4.5 X 10 (14),,, [ not the Gf itself] right?
 
how to get it in cgs units,,, I don't know how to use google to convert the units!
 
If you know it in Joules, just convert Joules to ergs.
You can do it in your head if google fails you.
 
what is then Gf2=5.29 * 10-38 cm2/GeV2?
