| | The Unified Code for Units of Measure |
 | | In short, each unit is defined relative to a system of base units by a numeric factor and a vector of exponents by which the base units contribute to the unit to be defined. |
 | | Fortunately these units are rather rare in everyday use in trade and medicine, however, we must urge everyone to regenerate their tables, dictionaries, and knowledge bases, and check their data immediately based on this corrected release of The Unified Code for Units of Measure. |
 | | The units directly affected by this error were: unified atomic mass unit (u), parsec (pc), Planck's constant [h], Boltzman's constant [k], electric permittivity ([eps_0]), elementary charge ([e]), electron mass ([m_e]), proton mass ([m_p]), Newton's constant of gravitation ([G]), Maxwell (Mx), Gauss (G), phot (ph), Curie (Ci), Roentgen (R), and U.S. and international mil ([mil_i], [mil_us]). |
