Description

Currency Converter Calculator helps visitors convert prices and amounts without leaving your page.
Add live currency conversion to pricing pages, tourism and travel guides, news websites, finance articles, business pages, and sidebars with a shortcode or classic widget.

Visitors get instant currency context in the place where they are already reading, shopping, comparing, or planning.
Site owners get a lightweight setup: no API key, no local rate database, and no exchange-rate processing load on WordPress.

⭐ What makes it useful

  • 🌍 190+ currencies and assets, including popular cryptocurrencies and metals.
  • 💱 Live currency conversion directly inside posts, pages, sidebars, and footers.
  • 🧩 Add the converter with a shortcode, the Shortcode block, or a classic WordPress widget.
  • ⚡ No API key, local exchange-rate database, or exchange-rate processing load on your WordPress site.
  • 📱 Responsive layout for desktop and mobile visitors.
  • 🎨 Color themes, background color, large mode, and corner style options.
  • 🌐 Multilingual widget labels for international audiences.
  • 🕒 Time zone setting for the displayed update date.
  • 🔒 SSL-ready CurrencyRate.Today service URLs.

🎯 Where it works best

  • Pricing pages where visitors need to understand a price in their own currency.
  • Tourism and travel websites where readers estimate trip costs.
  • News websites that cover markets, business, inflation, travel, or international stories.
  • Finance blogs that need a simple converter next to rate commentary.
  • Business and service pages for international customers.
  • Multilingual sites that need converter labels in the visitor’s language.

👀 Demos

🚀 Quick start

  1. Install and activate Currency Converter Calculator.
  2. Paste the shortcode into a post, page, or Shortcode block.
  3. Choose the source currency, target currency, language, theme, background, and layout.

FAQ

How do I add the converter to a page or post?

Use a shortcode or paste it into a Shortcode block:

[ccc_currency_converter_calculator lg="en" tz="0" fm="EUR" to="USD" st="info" bg="FFFFFF" lr="1" rd="0" size_width="100%"][/ccc_currency_converter_calculator]

Can I show the converter in a sidebar?

Yes. Add “Currency Converter Calculator” under Appearance > Widgets.
If your WordPress site uses the block-based widget screen, install and activate Classic Widgets first.

Do visitors leave my website to convert currencies?

No. The converter is embedded directly on your page, post, sidebar, or footer.

Does the plugin require an API key?

No. Exchange-rate lookup and display are handled by the embedded CurrencyRate.Today service, so you do not need an API key or local rate database.

Can I choose currencies, language, and theme?

Yes. You can choose the source currency, target currency, language, time zone, color theme, background, size mode, corner style, and width.

Which shortcode attributes are available?

The main attributes are lg, tz, fm, to, st, bg, lr, rd, and size_width.
See the shortcode attributes section above for the full list.

External service and privacy

Yes. The plugin embeds an iframe from CurrencyRate.Today.
When a page containing the converter is viewed, the visitor’s browser requests https://currencyrate.today/load-converter.

The request includes display settings such as source currency, target currency, language, theme, time zone, background color, and widget size.
These values come from the shortcode or widget settings.

The plugin does not send WordPress usernames, passwords, admin settings, or private site data to the service.

Service provider: CurrencyRate.Today

Does the plugin include a Gutenberg block?

No. The plugin currently supports shortcodes and classic widgets. In the block editor, use a Shortcode block.

everthing was good unless html output language can not be changed, even if you edit php files. the plugin will be more useful and reach more user if output language can change by the site admin. because this reason i have to uninstall it 🙁
