American Exchange Rate Calculator
This calculator helps you convert amounts between USD and other major currencies using current exchange rates. Simply enter the amount you wish to convert and select the target currency.
Understanding Exchange Rates
An exchange rate is the value of one country's currency for the purpose of trading for another. For example, if the EUR/USD exchange rate is 1.10, it means that one Euro can be exchanged for 1.10 US Dollars. Exchange rates are constantly fluctuating due to various economic and political factors, including inflation, interest rates, political stability, and market speculation. This calculator provides an estimate based on commonly referenced rates. For precise real-time rates, it's always best to consult a financial institution or a dedicated financial data provider.
How it works:
- Amount to Convert: Enter the numerical value of the currency you wish to exchange.
- From: Select the currency you are converting from.
- To: Select the currency you want to convert to.
The calculator will then display the equivalent amount in the target currency. Remember that actual rates obtained from banks or exchange services may include fees and slightly different conversion values.
function calculateExchangeRate() {
var amountInput = document.getElementById("amount");
var fromCurrency = document.getElementById("fromCurrency").value;
var toCurrency = document.getElementById("toCurrency").value;
var resultDisplay = document.getElementById("result");
var amount = parseFloat(amountInput.value);
if (isNaN(amount)) {
resultDisplay.textContent = "Please enter a valid number for the amount.";
return;
}
