What is the weight I would need to make business cards with? Is 120lb thick enough?

I would check with your printer to see how heavy of a stock that you can print on.  People use several different weights for business cards.  Any where from 80 lb up to 130 lb.

how thick is this in millimeters?

I am sorry, but we are unable to give measurements in mm.  Our paper is measured in cover weight and gsm.
