are these two units of viscosity are same or different
mPa.s & gram-forcesecond/cm2.

as per my calculation 1Cp= 0.0000102 mPa.s
as per online conversion 1Cp=0.0000102 gram-forcesecond/cm2.

A centipoise is indeed equal to 1 millipascal second.

Though I should note the correct symbol for the centipoise is cP.

I want to know the conversion from SUS to cst

are these two units of viscosity are same or different
mPa.s & gram-forcesecond/cm2.

as per my calculation 1Cp= 0.0000102 mPa.s
as per online conversion 1Cp=0.0000102 gram-forcesecond/cm2.

Here is the information I found:

For liquids whose viscosity exceeds 50 centistokes at 37.8 °C (100 °F) one SSU is approximately 0.2158 centistokes or 0.2158 mm2/s. For very viscous liquids (viscosity exceeding 500 centistokes) at 50 °C (122 °F), one SSF is approximately 2.120 centistokes or 2.120 mm2/s.

For exact equations, need to find an article published in 1996 by the American Society for Testing and Materials (ASTM practice D2161). I tried searching but found nothing.

I have an unrelated question: If specs are 5.5-24 mm2/s, then when I run the material on a dynamic viscometer, what is that range in cP? I'm having issues trying to find a quick/easy conversion, any comments are appreciated :) Thanks!

i want converstion for 108mm2/s is how much of m3/kg

what is cps related to viscosity?
