Uncertainty notation[edit]

1.054 571 628(53) x 10^–34 J s means that the value is 1.054 571 628 x 10^–34 J s and its standard uncertainty is
0.000 000 053 x 10^–34 J s. An estimated standard deviation, termed standard uncertainty, is equal to the positive square root of the estimated variance. ^[1]

Guide for Metric Practice[edit]

Internationally recognized conventions have been established for standard usage of SI units. http://www.aip.org/pt/guide/metric.html

cm^–1[edit]

Unit of wavenumber nu-bar is cm^–1
E [J] = h [J s] × c [cm/s] × nu-bar [1/cm] = 1.9865×10^–23 × nu-bar
nu [1/s] = c [cm/s] × nu-bar [1/cm] = 3×10¹⁰ × nu-bar [1/cm]
