Physical Constants¶
SIMION 8.1.0 uses CODATA2010 constants (see Wikipedia:CODATA). This differs from the 8.0 manual.
In SIMION 6.0/7.0/8.0, the constants are CODATA1986 values. Dahl2000 notes “The physical constants used in version 6.0 and 7.0 are from the 74th edition of the CRC Handbook of Chemistry and Physics [12] Values of these physical constants (e.g. c, electron mass, and elementary charge) are defined to 8 or 9 significant place accuracy”. The 74th edition (1993-1994) uses CODATA1986, which were the latest CODATA values at that time. SIMION 8.0 also uses these constants.
