Understanding Currency Exchange Rates
Currency exchange rates are the value of one nation's currency for the purpose of trade.
They fluctuate constantly due to a variety of economic and political factors, including
interest rates, inflation, political stability, and market speculation. When you exchange
one currency for another, you are essentially buying or selling one currency against another
at the prevailing market rate.
This calculator helps you quickly determine how much of a target currency you would receive
for a given amount of your source currency. Simply enter the amount you wish to convert,
select your starting currency, and choose the currency you want to convert to. The calculator
will then provide an estimated converted amount based on current market dynamics.
Important Note: The exchange rates used in this calculator are for illustrative
purposes and may not reflect real-time interbank rates or the exact rates offered by
banks or currency exchange services, which often include a margin or fee. For precise
transactional rates, please consult your financial institution.

var amountToConvert = parseFloat(document.getElementById("amountToConvert").value);
var sourceCurrency = document.getElementById("sourceCurrency").value;
var targetCurrency = document.getElementById("targetCurrency").value;
// Define some example exchange rates (these are static for demonstration)
// In a real application, you would fetch these from a live API.

// For a robust solution, ensure all inverse rates are available or calculate them.
