We are also using RBI rates for the conversion but some of the vendors/sellers of books have the objection. They ask us "RBI do not sell any currency and they provide the indicative rates only and based on these indicative rates other Banks are doing business and fix the rates of buying and selling of foreign currency". It is my personal opinion that you may select the bank rates of a nationalized bank in which your institution has the bank account. -- *M.K.
