All good DROs and electronic micrometers and calipers will switch between metric and standard. I prefer Mitutoyo, but that is just me. DO NOT buy Mitutoyo off of sites like eBay or even Amazon because there is a high probability of them being counterfeit.
I have bought items from this site.

I use Noga for indicator holders with the bottom fine adjustment.
