Come on man.... At least try it on a calculator, or Google!
Hey, if he doesn't know that m means milli, or doesn't know what milli is,
then how would his calculator help?
A millivolt is a thousanth of a volt, so 200mv is 0.2v.
On the other hand, just for fun I looked it up on Gurunet while I was typing
this, and it gave me the answer; so maybe your criticism isn't too far off.
