Chemistry Conversion Factors And Constants Pdf This document provides conversion factors and constants for various units used in mechanical engineering. it includes conversions for temperature, length, volume, mass, force, pressure, energy, power, density, specific weight, and air properties. Geometrized to standard conversion: replace quantities in column 2 with quantities in the last column. standard to geometrized conversion: multiply by the factor of g and c appearing in the last column. Selected fundamental constants and conversion factors values of selected fundamental constants speed of light in a vacuum (c) charge on an electron (e) rest mass of an electron (me) = 2.99792458 108 m s. Selected physical units in the si and gaussian systems. this table does not include the secondary units (e.g., those of velocity, torque, etc.) that have no special names symbols in either system and are related to the listed units in an obvious way, and also the units (e.g., of luminous intensity, catalytic activity, etc.) not used in this series.
