Bohr Magneton: Value

The value of the Bohr magneton is:

\(\ds \mu_{\mathrm B}\)

\(\approx\)

\(\ds 9 \cdotp 27401 \, 00783 \, (28) \times 10^{-24} \, \mathrm {J \, T^{-1} }\)

This sequence is A234371 in the On-Line Encyclopedia of Integer Sequences (N. J. A. Sloane (Ed.), 2008).

\(\ds \)

\(\approx\)

\(\ds 9 \cdotp 27401 \, 00783 \, (28) \times 10^{-21} \, \mathrm {erg \, Gs^{-1} }\)
