Viscosity
The following table displays common viscosity values in degrees F from the NSWC-98/LE1standard for several mechanical parts. Keep in mind that you always enter temperatures in the Prediction module in degrees C so that you can mix models or change the top-level calculation model. For parts supported by the mechanical model, all necessary conversions from degrees C to degrees F are handled internally.
