Can anyone tell me how to convert Dialog units to pixels?

Paper & Form Margins are in dialog units whilst the freeformat printing requires pixels to be specified.

To ensure I can line up data correctly I need to be able to convert one to the other rather than using trial and error for each Form.

Thanks

If these dialog units are twips, which I think they are, then this bit of information might help.

There are 1440 twips per inch.

A horizontal dialog base unit is one-quarter the average character width for the current system font, and a vertical dialog base unit is one-eighth the average character height for the current system font. I believe that a capital M is regarded as an average character in typography, so it should be possible to use the getTextExtent("M") and getTextHeight("M") methods to do the conversion?
