how to convert to metric system in visio 2003?
Don't be reluctant to tell us what you want to do. We can only guess
otherwise.
Do you want to use metric rather that imperial measurement templates
and stencils?
Do you want to convert current diagrams to metric?
Do you just want to show measurements in metric units?
Metric templates and stencils may not have been installed on your
system.
Use menu Tools -> Options to set the default measurement types.
