Currency Converter

A currency converter is a tool that helps convert one currency to another. Currency conversion is the process of changing the value of one currency into the equivalent value of another currency. Currency converters are widely used by individuals, businesses, and governments to facilitate international trade, finance, and travel.

Concepts and Formulae

Currency conversion is based on the principle of exchange rates, which represent the price of one currency in terms of another. Exchange rates are constantly changing due to a variety of factors, including economic conditions, political events, and supply and demand.

The basic formula for currency conversion is:

Amount in Foreign Currency = (Amount in Home Currency) × (Exchange Rate)

Where:

• Amount in Foreign Currency is the amount of the foreign currency you want to convert to
• Amount in Home Currency is the amount of the home currency you have
• Exchange Rate is the price of one unit of foreign currency in terms of home currency

For example, if the exchange rate between the US dollar (USD) and the Japanese yen (JPY) is 120 JPY/USD, it means that one USD is worth 120 JPY. To convert 100 USD to JPY, you would use the following formula:

Amount in JPY = (100 USD) × (120 JPY/USD) = 12,000 JPY
