In addition to the standard units of measure provided by the ADTS, two user-defined units are
available. To create a user-defined unit, the user enters a name that is one to ten characters long
and a conversion factor that is a multiple of kiloPascals (kPa).
For example, using the information from Table 2-1, the conversion factor for millitorr or one
micron of mercury at 0 °C is calculated as follows:
mTorr
Thus the conversion factor simplifies to
