# nuclear magneton in eV/T, CODATA 2022 (NIST)
nuclear_magneton_in_ev_t = 3.15245125417e-8 # eV T^-1, standard uncertainty 9.8e-18
# SciPy: scipy.constants.physical_constants['nuclear magneton in eV/T']What it is
The nuclear magneton expressed in electronvolts per tesla.
How the value changed, 1998–2022
Each point is one CODATA adjustment, plotted as its difference from the 2022 value; the bars show one standard uncertainty (an arrowhead means the bar runs off the chart).
Relative uncertainty
| CODATA | Value (uncertainty) | Relative uncertainty | Change from previous |
|---|---|---|---|
| 2022 | 3.152 451 254 17(98) × 10−8 | 3.1 × 10−10 | −4.4 σ of 2018 |
| 2018 | 3.152 451 258 44(96) × 10−8 | 3.0 × 10−10 | +2.3 σ of 2014 |
| 2014 | 3.152 451 2550(15) × 10−8 | 4.8 × 10−10 | −2.5 σ of 2010 |
| 2010 | 3.152 451 2605(22) × 10−8 | 7.0 × 10−10 | +6.2 σ of 2006 |
| 2006 | 3.152 451 2326(45) × 10−8 | 1.4 × 10−9 | −1.3 σ of 2002 |
| 2002 | 3.152 451 259(21) × 10−8 | 6.7 × 10−9 | +0.9 σ of 1998 |
| 1998 | 3.152 451 238(24) × 10−8 | 7.6 × 10−9 |
“Change from previous” is the shift in the value divided by the standard uncertainty of the previous adjustment. Earlier values are converted into the current unit where NIST changed it (for example J s to J Hz⁻¹).
