Euro FxRef Currency Converter


Using the [currency] shortcode you can convert one currency to another. The conversion is based on the rates published by the ECB. You can change from and to any of the supported currencies.

The [currency_legal] shortcode outputs a disclaimer text and a link to the ECB eurofxref page.


ECB advices against using their rates for transaction purposes. From their site: « The reference rates are published for information purposes only. Using the rates for transaction purposes is strongly discouraged. »

The reference rates are usually updated by ECB at around 16:00 CET every working day, except on TARGET closing days.

Go to the ECB site for more information and disclaimers.

Also note that conversion from non-Euro to non-Euro is done through the Euro, so GBP to USD is calculated as GBP → EUR → USD (converted 2 times).

This plugin is based on a plugin by Xclamation.

Also see wp_eurofxref on GitHub where development takes place.

Shortcode usage & examples

currency_legal shortcode

This shortcode returns the string ‘* For informational purposes only. Exchange rates may vary. Based on ECB reference rates.’

The prepended ‘* ‘ (the same string as the [currency] append string) can be changed using the ‘prepend’ attribute.

For example: [currency_legal prepend='Please note: ']

If you want to change the default prepent string for your whole site you can use the default shortcode_atts_currency_legal filter.
See the shortcode_atts_{$shortcode} reference for more information about this.

currency shortcode


  • from: currency code (default: EUR)
  • to: currency code (default: USD)
  • amount: number of « from » currency (default: 1)
  • iso: boolean (default false); use ISO currency formatting. »€ 1″ would become « 1 EUR » in ISO notation.
  • show_from: boolean (default true); show from amount in output
  • between: string (default ‘ / ’ which is displayed as ‘ / ‘ in the browser); string between from and to amounts
  • append: string (default ‘ ‘ which is displayed as ‘ ‘ in the browser); string put after conversion. The * references the disclaimer text, see [currency_legal] shortcode.
  • round: boolean (default true); Round numbers to whole units.
  • round_append: string (default ‘=’); replaces decimals
  • no_from_show_rate: boolean (default true); when from amount is hidden in the output the « to » text gets a tooltip that displays the exchange rate. The <span> element with this tooltip is styled with the to_style css string below. Set the no_from_show_rate option to false to disable the <span> and tooltip.
  • to_style: css string (default ‘cursor:help;border-bottom:1px dotted gray;’); styling of « to » text <span> wrapper.

If you want to change the defaults for your whole site you can use the default shortcode_atts_currency filter. See the shortcode_atts_{$shortcode} reference for more information about this.


  • [currency amount="875" from="EUR" to="GBP"]
    becomes « € 875,= / £ 697.= * »
  • [currency amount="875" from="GBP" to="USD" iso=true between=" converts to " append="" round_append=""]
    becomes « 875 GBP converts to 1,418 USD »
  • [currency amount="875" from="GBP" to="USD" show_from=false round=false]
    becomes « $ 1,130.15 * »

Where do the exchange rates come from?

The European Central Bank (ECB) daily publishes « foreign exchange reference rates » against more than 30 other currencies. These rates are used by this plugin.

The rates are published for informational purposes only and exchange rates may vary.

See the ECB site for more information.

What styling options do I have?

When not showing the ‘from’ value the converted amount is wrapped with a <span> with css styling that is configurable using the ‘to_style’ attribute.

Since v2.0 of the plugin additionaly the following classes are available to style using CSS:

  • ‘eurofxref-conversion-rate’ to overrule the ‘to_style’ attribute value of the [currency] shortcode.
  • ‘eurofxref-append-string’ on a <span> wrapping the ‘ *’ text of the [currency] shortcode.
  • ‘eurofxref-prepend-string’ on a <span> wrapping the ‘* ‘ text of the [currency_legal] shortcode.

What filters are available?

Since v2.0 the following filters are available:

  • ‘shortcode_atts_currency’ to modify the [currency] shortcode attributes.
  • ‘shortcode_atts_currency_legal’ to modify the [currency_legal] shortcode attributes.
  • ‘eurofxref_currency_symbols’ to modify the currency symbols used in your site. The symbols are also run through the ‘woocommerce_currency_symbols’ filter so you don’t need to use both.
  • ‘eurofxref_number_formats’ to modify the currency number formatting used in your site.

Exactly what I needed for my client’s tour website. The tour price is in euros but many of the customers are British or American. Now we can give customers an idea of the cost in their currencies. Thank you!

Contributors & Developers

“Euro FxRef Currency Converter” is open source software. The following people have contributed to this plugin.




  • The plugin now tries to retrieve the new ECB rates around 17h00 CET. ECB updates their rates around 16h00 CET so updating an hour later should retreive the newest rates.


  • Bugfix when [currency_legal] is called without attributes.


  • Added no_from_show_rate shortcode attribute for the [convert] shortcode.
  • Added an option to hook into the default shortcode_atts_{$shortcode} filter for both shortcodes. Those filters become ‘shortcode_atts_currency’ and ‘shortcode_atts_currency_legal’. Please see shortcode_atts_{$shortcode} reference for more information.
  • Updated list of available currencies based on changes by the ECB (RUB and HRK where removed).
  • Refactor of currency symbols and number formats based on how WooCommerce does it.
