All experimental data curves must have the same units.

The unit conversion described in Converting to a New Unit System is performed only for quantities in the Material Data menu in Ansys Polymat. Other parameters (data curves, numerical parameters, temperature at which a viscosity curve is to be computed, and so on) must be in the new unit system; they will not be converted for you.

If you save a material data file in a new unit system (for example, CGSA + Celsius) and you use it in an Ansys Polydata session where MKSA + Kelvin units are being used, be sure to convert the material data to MKSA + Kelvin in Ansys Polydata, as described in the Ansys Polyflow User’s Guide.
