To convert 100 USD to Japanese Yen, you would typically use the following expression:
100 USD * exchange rate (USD to JPY)
In this expression, the exchange rate represents how many Japanese Yen are equivalent to one US Dollar. For instance, if the current exchange rate is 110 JPY for 1 USD, the calculation would look like this:
100 USD * 110 JPY/USD = 11,000 JPY
It’s essential to check the current exchange rate, as it fluctuates continuously due to market conditions. Additionally, you may want to consider any transaction fees that might apply when you exchange currencies.
