[Gimp-user] How do I use measure tool in mm

[Jay Smith]

Using Gimp 2.6.6 on Ubuntu 8.04 (Hardy) Linux.

I can't seem to figure out how to get the measure tool to show results
in mm.

So far the only way I have been able to figure out how to measure in mm
is to: select the region I wish to measure, copy, create from clipboard,
and then use one of the print size or scale dialogs and change the units
in that dialog to mm.

There has to be a better way.

Thanks.

Jay
