Ohio Rev. Code § 2712.71: Relief granted in foreign currency.

The courts of this state shall confirm a final award, notwithstanding the fact that it grants relief in a currency other than United States dollars. In such a case, the court, in addition to entering the order in a foreign currency designated by the award, upon application by a party also shall enter that order in United States dollars determined by reference to the market rate of exchange prevailing in this state on the date the award was issued, unless the award itself fixes some other date. If no such market rate of exchange is available, the court shall fix the rate it determines to be appropriate.
