Analogous to the SI the Application Server defines seven base quantities. Table 1 shows these base quantities along with their corresponding SI base units and dimensions.

Other quantities, called derived quantities, are defined based on these seven base quantities via a system of quantity equations. Each derived quantity can be expressed as term consisting of only base quantities as shown in figure 1.

The derived units for derived quantities are obtained from these equations and the base units. Note that the Application Server only supports unit systems that work define the same base units and that define derived units in the same way.

For ease of understanding and convenience 22 SI derived quantities and units have been given special names and symbols. Table two lists these 22 derived quantities together with their SI  unit name and symbol. The expression to derive those units from other SI units can of course be expanded to use only SI base units.
