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	C F K R	degree radian

Derived Units

The following additional pre-defined derived units are also available on the Units tab of the Units Manager dialog box.
