This proposal is years out of date. It needs to be updated with microformats2 and using modern currency-examples. - Tantek 23:26, 18 March 2013 (UTC)



currency is a simple microformat for marking up money amounts, such as prices of products/services or financial facts.

Note: an alternative proposal can be found at measure, treating currency as simply a specific kind of measurement.


Money amounts are one of the most widespread content found on the Web, but the lack of unambiguous representation of the currency they are expressed in, or the date that they relate to, makes comparison and matching of offerings online difficult.


This proposal was written based on the contributions of several members of the community. Original brainstorming ideas and strawman proposal can be viewed at currency-brainstorming and currency-brainstorming#Andy_Mabbett


This proposal limits its scope to:


Root Class Name

The root class name for a money amount is money.

Property List


Simple in-line example with local definition of the currency unit: $39.99

<span class="money"><abbr class="currency" title="USD">$</abbr><span class="amount">39.99</span></span>

Text representation of the amount: Thirty-nine Dollars

<span class="money"><abbr class="amount" title="39">Thirty-nine</abbr> <abbr class="currency" title="USD">Dollars</abbr></span>

Example using the unit class: 99¢

<span class="money"><span class="amount">99</span><abbr class="unit">¢</abbr><abbr class="currency" title="USD"></abbr></span>

Table example with global definition of the currency:

      <tr><th>Price in <abbr id="u1" class="currency" title="USD">US$</abbr></th></tr>
      <tr><td><div class="money">39.99<a href="#u1" class="include"></a></div></td></tr>
