How to calculate the temperature accuracy from RTI accuracy voltage ?

Hi..
I calculated the system accuracy = +/- 0,9 mV which the system accuracy RTI=0,018%

I connect PT100 to SCXI1121+DAQ6052E.

That I need is the accuracy in °K

If I use (system accuracy RTI)0,018% * 300 (Full scale of Temperature) and I get +/- 0,05°K, is that correct ?

I already read from

"Finding the Accuracy of Measurements in the Units of a Sensor" http://digital.ni.com/public.nsf/websearch/99173BA39CEC612986256CFF000A933E?opendocument&Submitted&&node=133020_US

But I don't really understand how to convert from mV back to Temperature again. Is that depend on some special factor?

The next point, is I used interpolation method. The output temperature is also depend on the ca
libration curve. ---> How can I convert back in this point.

Thank you very much for any kind help.
