In DatadiagramML, however, even though the unit type information is stored, the value of an element is expressed in whatever the appropriate <i>internal units</i> are for that value. An internal unit is the unit of measure used by Microsoft Office Visio to represent a particular type of value and is the value Visio writes to DatadiagramML files.</p><p>For example, values representing units that are a measurement of length are expressed as floating-point numbers in inches, because the inch is the internal unit used by Visio to represent length. Therefore, if an element has a value of "2 feet", its <b class="bterm">Unit</b> attribute is <code>'FT'</code> for "feet" and its value is the number 24.</p><p>Other units, such as date/time, are expressed as formatted strings. In the case of date/time, the unit is a string, such as "2004-12-20T23:00:00".</p><p>If a unit of measure is explicitly set, and if it is different from the default unit for the cell, Microsoft Office Visio writes out the <b class="bterm">Unit</b> attribute in DatadiagramML files. If no <b class="bterm">Unit</b> attribute is present in an element that represents a cell, Visio will use the default unit for that element.</p><p>For more information about how units of measure work in Visio, see <a target="_blank" href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vissdk11/html/DSS_CTSShapeSheetBasics_1828.asp" id="HV82251828" lcid=" ">About units of measure</a> in the Microsoft Office Visio ShapeSheet Reference.</p><p>The following tables describe valid units of measure and provide information about internal units and how they are expressed in a DatadiagramML file. </p>

A value of "12 points" would be expressed as: <p><pre><code><Size>0.16666666666667</Size></code></pre></p>
