Theorem

The gyromagnetic ratio of the proton is given by:

\(\ds \gamma_{\mathrm p}\) \(\approx\) \(\ds 2 \cdotp 67522 \, 18744 \, (11) \times 10^8 \, \mathrm {rad \, s^{-1} \, T^{-1} }\)
\(\ds \) \(\approx\) \(\ds 2 \cdotp 67522 \, 18744 \, (11) \times 10^4 \, \mathrm {rad \, s^{-1} \, Gs^{-1} }\)

which gives the mantissa as $2 \cdotp 675 \, 196 \, 5$, with an uncertainty of $\pm 82$ corresponding to the $2$ least significant figures
