So, let's say you run a UK based site and will refer to currencies in GBP. However, the majority of visitors are from the US, so you may have a wish to also show the dollar equivalent. Using this plugin you can do this without having to work out the conversion and then re-visit it in future to take into account conversion changes.
Features include...
- No need to update exchange rates yourself - data is fetched from an Open Source API
- Over 170 currencies supported
- An easy to use shortcode for embedding directly into your posts and pages
- A PHP function for those people who wish to add features in their theme
- Results can be cached, reducing resources and improving response
- Template to allow you to control how results are output
- Administration screen allowing you to define defaults and to view current exchange rates
