The nuclear magneton expressed in inverse metres 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 | 2.542 623 410 09(79) × 10−2 | 3.1 × 10−10 | −4.4 σ of 2018 |
| 2018 | 2.542 623 413 53(78) × 10−2 | 3.1 × 10−10 | −1.2 σ of 2014 |
| 2014 | 2.542 623 432(16) × 10−2 | 6.3 × 10−9 | −1.7 σ of 2010 |
| 2010 | 2.542 623 527(56) × 10−2 | 2.2 × 10−8 | −1.4 σ of 2006 |
| 2006 | 2.542 623 616(64) × 10−2 | 2.5 × 10−8 | +0.2 σ of 2002 |
| 2002 | 2.542 623 58(22) × 10−2 | 8.7 × 10−8 | −0.8 σ of 1998 |
| 1998 | 2.542 623 66(10) × 10−2 | 3.9 × 10−8 |
“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).
