SUMMARY
The discussion clarifies that base oil viscosity in grease is measured in centistokes (cSt) and square millimeters per second (mm²/s), which are equivalent units for kinematic viscosity. Specifically, 200 cSt is the same as 200 mm²/s. The conversation also highlights that 1 Stokes equals 1 cm²/sec, and 1 centistoke equals 1/100 Stokes, reinforcing the relationship between these units. Understanding these units is essential for accurately interpreting viscosity ratings in lubricants.
