Question about viscosity and permittivity units

[Lane Votapka]

Hi Gary,

I'm looking at the results.xml file, trying to use Browndye 2 to recreate a Smoluchowski eq. calculation, and I'm not sure what units are being used in the values for permittivity and water viscosity:

<vacuum_permittivity> 0.000142 </vacuum_permittivity>
<water_viscosity> 0.243 </water_viscosity>

In my Smoluchowski calculation, I'm using a viscosity of 0.89 cP, (which is 8.9e-4 Ns/m^2), and I'm using a permittivity of 8.854 C^2/Jm.

How can I convert between these units to verify that I'm using the same values?
