By default, all material data inputs to Ansys Polymat are in the international MKS (meter, kilogram, second) unit system. You can, however, change to a different unit system, such as the CGS (centimeter, gram, second) system. You can also specify different units for individual quantities (length, mass, time, temperature, or electric current), rather than using a standard system of units. This allows you to customize the units to match your data, thus simplifying the setup procedure by eliminating the need to convert the units yourself.

For example, if your viscosity data is in poise (g/s-cm) instead of Pa-s (kg/s-m), you should change the length units from meters to centimeters and the mass units from kilograms to grams.
