Section 7.1 gives examples illustrating the use of quantity calculus for converting the values of physical quantities between different units. The table in section 7.2 lists a variety of non-SI units used in chemistry, with the conversion factors to the corresponding SI units. Conversion factors for energy and energy-related units (wavenumber, frequency, temperature and molar energy), and for pressure units, are also presented in tables inside the back cover. 

The valve conductance, C,. (m ), will be available from manufacturer s data (it may be necessary to use the US to SI units-conversion factors given in Appendix 3). However, before we can calculate the friction coefficient, C/,a, at high-pressure ratios, we need to know the valve conductance to the throat, Crt, which, as we have seen from equation (9.9), depends on the throat area. A,. This last parameter may be inferred from the limiting gas conductance, Cg.
