Currency Conversion Rates, provides the option of fixing the conversion rate you want to publish on your website.
For example if you are a reseller and you intend to publish the price in USD, because your target market are Americans. However, your supplier has not defined his own prices in USD so you will have to convert the prices e.g. from ISK to USD to publish on your web.

Even so, you might have your own fixed currency conversion rate you want to use. In that case it is possible to override the default setting and add the conversion rate you want to use.
Choose the "Menu Icon in top left corner" on the top bar and the select "Currency conversion rates" from the drop down list.
