Conversion Units

Emission Master performs unit conversions during its operation based on the users default settings (See Options/Units) and based on the requirements of the individual equations.  The following conversion factors are being used by the program as obtained from "Dictionary of Scientific and Technical Terms", McGraw-Hill, 1983.
