Viscosity Cst 100C vs SUS viscosity at 210 F

[D-Roc]

I've been looking at some of my old Blackstone UOA's and mine all came in SUS Vis/210F. Now I see most people have their's in Cst @100c. Is this a choice when using Blackstone? I find Cst a little easier to comprehend, as I don't know the range for SUS @210F...
Also, can someone point me in the direction of a chart so I can compare Cst and SUS for 30 and 40 weights? IE, something that has both and where they meet (if a chart like that is available).
Thanks

My understanding is that Blackstone decided to include cSt due to customer feedback.

Here is a chart. An equation relating the two would be more accurate than using the chart but I didn't search for that.

I found the equation relating cSt and SUS.
cSt = 0.22*SUS - 180/SUS

Awesome, thanks. Its nice to have both as sometimes you see values given in the one you're not used to using...
Thanks, Jag.
