O-Calc Pro provides a complete set of routines for performing all of the units conversion that might be required by O-Calc developers.

It is important to understand that the stored units and the displayed units in O-Calc Pro are not always the same. The integrated Schema Explorer tool allows you to find the name and stored units of any attribute in the O-Calc data model.

Access to the units conversion routines are via the PPL_Lib.PPLGridModel.Attribute namespace and the methods provided are as follows.
