Convert Measurement Units
IronDrawing provides an option for users who want to change the measurement unit used in Rectangle or RectangleF from pixels (px) to millimeters (mm) or vice versa. The default measurement unit used in Rectangle and RectangleF is pixels (px).
After a new Rectangle with measurements specified has been instantiated, you can call the conversion method on the Rectangle. For example, use .ConvertTo(MeasurementUnits.Millimeters, 20). This will convert the measurements of the Rectangle to millimeters based on the DPI set by the user. This same approach can also be applied to the RectangleF class.
