Viscosity of SAE 30 oil? Help plz!?

What is viscosity of SAE 30 oil at 60 degrees fareinheit in US customary units. I cant find it on the net anywhere.Viscosity of SAE 30 oil? Help plz!?
It has a cSt of about 65 at 120 degrees Farenheit, which would put it in the ballpark of about 200-280 at 60 degrees Farenheit, assuming it was a regualr SAE 30 ooil and did not have viscosity additives for winter or temperature regulated usage (as most motor oils do nowadays).Viscosity of SAE 30 oil? Help plz!?
kinematic viscosity units are centistokes (cST)





There is a publication at the following website:





http://www.terratherm.com/company/SOQ.pd鈥?/a>





on page 8 of the document SOQ.pdf there is a graph of viscosity vs temp for various oils, reading the graph for SAE 30 oil at 60 degrees F gives the value 340. Reading the graph for SAE 30 oil at 212 F gives the value of 10.





The SAE specification for SAE 30 oil is 9.3-12.5 cST @ 100 C (212 F) use midpoint number: 10.9 cST @ 212 F, so this corresponds with the value in the graph on page 8 of the above document.





So the viscosity of SAE 30 oil at 60 F is about 340 cST.





here's a good description of choosing viscosity of lubricating oil for automotive engines:

Motor Oil that is measured to have viscosity of 9.5 cSt @ 100 C will be rated as SAE 30.





P.S - I have no idea about what cSt stands 4.
