Unit conversions in AppleScript

[dmw]

I'm doing some custom scripting to create some documents in OG Pro. I can't quite figure out the units. From my script, I've created a new document from a template, with the ruler set to use centimeters. My question is, how can I specify my units using the same units as the ruler? That is, a rectangle created with a size of (100, 100) should be 100cm x 100cm.

Please let me know if there is a better forum for scripting questions.

Thanks
