Convert Japanese Yen to South Korean Won when you are checking Yen against Won, two large-unit currencies. Neither side is the Euro, so JPY/KRW is a cross rate derived from the ECB’s Euro reference rates.
The Yen is quoted in larger units than the Dollar or the Euro, so the converted total is usually a much bigger number. The South Korean Won, like the Yen, is quoted in large units. The table multiplies 1, 5, 10, 50, 100, 500, and 1,000 Japanese Yen by that same rate. Banks, bureaux, and card networks usually take a spread on top, so treat the result as a baseline rather than the quote you will be offered.
