Silver: 0.3mm - or about 0.012 inch.
Copper: 0.1mm - or about 0.004 inch.
1mm is equal to about 0.040 inch - it's actually 0.039 . . . something, but close enough for this purpose.
Yes, you'll need a digital caliper. 
Hey Gav
thanks for clearing up one thing with the mm's and the inches
how do novarossi engines come out in terms of shims installed when the engine is new?
