can we have different picklist values based on logged in user country?...for example

I have a picklist field called "unit of measurement" in Account object having values (m,cm,km,mm). The requirement is if thailand user logged in , i just need to see (m,cm,km). i don't want mm to be displayed for those users. and for all other users picklist values should be (m,cm,mm). Record types are global for all the users....it should be implemented in Account standard page layout.
please suggest a solution for this other than RECORD TYPE.
