Converting dynamic (cP) Viscosity to Kinematic (cst) Viscosity
Converting dynamic (cP) Viscosity to Kinematic (cst) Viscosity
(OP)
I am working with an equation for an excel spreadsheet. Our brookfield viscometer reads in cP and I need to convert this to cst in order to make a viscosity curve. Any help would be greatly appreciated. Thanks Again

http://www.google.com --> "dynamic kinematic viscosity" --> first result. this is really lazy.

RE: Converting dynamic (cP) Viscosity to Kinematic (cst) Viscosity
I could never remember whether I should multiply or divide by the density, so I included a calculator to do this conversion, using a wide variety of units for the viscosities and density, in my freeware program called Uconeer.
Uconeer can be freely downloaded and used. See www.katmarsoftware.com

(btw, I had deleted the older version, and it messed up my icon for the new one, so I needed to download it again.)
Thanks, Harvey.

Don't be surprised to find that air (as well as many other gases) has a higher kin. visc. than liquid water!
At 300 K and atmospheric pressure:
Air: 15.7 cSt; liquid water: 0.86 cSt.
Any comment?
RE: Converting dynamic (cP) Viscosity to Kinematic (cst) Viscosity
Gases show very significant viscosity change with temperature (due to the increased collisions) but very little with pressure. Note also that viscosity increases with gas temperature and decrease with liquid temperature. Viscosity changes are negligable with pressure for liquids but can decrease significantly for a temperature increase.
Similar differneces (pardon my english!) with density.
