I often get asked if there's a metric version of my template. There isn't, but localizing the Shoegnome Open Template to whatever library you prefer and to meters/millimeters is fairly simple. In this video I cover both the conversion to meters and how to swap out the libraries. It's fairly straightforward and easy.
In the video around 1:45 I change the dimensions in the Project Preferences. You'll notice there are 8 buttons above where I change feet to meters. Each button controls a different type of dimensions in Archicad. To change a file from feet to meters, you need to change all 8 of these buttons (otherwise story levels, door and window markers, etc. will still show feet).
You'll also want to go through all the Project Preferences and change anything else there that relates to units (feet/meters).
