The currency converter lets you instantly convert any amount between 30 major world currencies. Exchange rates are fetched live from the ExchangeRate API each time you click Convertir, so results always reflect current market rates.

​
How to use

  1. Select the source currency from the Moneda dropdown (moneda_combo_box). This is the currency you are converting from.
  2. Enter the amount to convert in the amount field (monto_input).
  3. Select the target currency from the Cambio dropdown (cambio_combo_box). This is the currency you are converting to.
  4. Click the Convertir button. The converted amount appears in the result area (conversion_text), rounded to two decimal places.
You cannot convert a currency to itself. If both dropdowns show the same currency, an error dialog appears before any API call is made.
The amount field must contain a numeric value. Entering text or leaving the field empty will trigger the error: “Ingrese un valor numerico por favor.”

​
Conversion formula

The result is calculated by multiplying the entered amount by the live exchange rate returned by the API: 
result = amount × exchange_rate
For example, converting 100 USD to EUR when the rate is 0.92 gives 92.00 EUR.
