Predefined Units
Basic Predefined Units
You can combine predefined units with custom units to create a custom system of units.
The following basic predefined units for length, mass, force, time, temperature and angle are available in Creo Parametric:
 Length Mass Force Time Temperature Angle cm ft in micron mil m mm g kg lbm ounce-m mg slug ton-m tonne dyne kg-f kip kN lbf N ounce-f ton day hr micro-sec min msec sec week CFKR degree radian
Derived Units
The following additional pre-defined derived units are also available on the Units tab of the Units Manager dialog box.
