The MeasureConverter class provides a way to convert a measure in twips (twentieth of a point) to a value in another measuring unit. Twips are the measuring unit used by TXTextControl. Possible conversions are handled through the Unit property. The result of the conversion is a string or a double, which can be used to display the value for the user. This class can be used in XAML as a static resource to automatically convert bound property values.
Introduced: 16.0.
