Platinum prices are typically quoted in U.S. dollars (USD) per troy ounce. As with most commodities, platinum is usually quoted in USD, but prices may be converted to any local currency. For example, if one is located in the UK, they could simply take a current price of $1480 USD per ounce and convert that $1480 USD to British Pound Sterling (GBP) at current exchange rates to come up with the local currency price per ounce in England.
