Currency Converter

How to use the currency converter

1. Type the amount you want to convert.
2. Pick the currency you have in From and the one you need in To.
3. Read the result and the unit rate (for example, 1 USD = X ARS). Use the swap button to invert the pair.

You can also tap one of the popular conversions above, such as USD to ARS, USD to BRL or EUR to USD, to load that pair in one click.

Where the exchange rates come from

Rates come from the public open.er-api.com feed, which is based on USD and updated once a day. The converter divides the rate of the destination currency by the rate of the origin currency, so any pair works, not only the ones against the dollar. The update date is shown under the result and the rates are kept in memory for one hour while the page stays open.

Worked example

Say you want to convert 250 EUR to BRL. The feed gives every rate against the dollar, so the converter divides the rate of BRL by the rate of EUR to get the direct EUR to BRL factor, and then multiplies your amount by that factor. The unit rate shown under the result (1 EUR = X BRL) is exactly that factor, so you can check the math by hand: 250 times X. Swapping the pair inverts the factor, and the amount is shown with the usual currency formatting.

Reference rate, not a quote

The figure you see is a market reference value. The price a bank, card issuer or exchange house gives you adds its own spread, fees and cut-off times. In countries with several exchange rates, such as Argentina, the official rate used here can differ from parallel or financial rates, which this tool does not show. Use it to estimate prices, compare offers or price invoices, and confirm the final amount with your provider.

Useful for businesses selling in several currencies

If you sell, import or invoice in more than one currency, a daily reference rate helps you set prices and reconcile amounts. YoFacturo handles multi-currency sales, invoicing and inventory in one platform. This page is also available in Spanish as the conversor de moneda and in Portuguese as the conversor de moedas. For local rates, see the dollar in Brazil, Mexico andUruguay.
