how to switch to metrical units

[aaronias]

hi,

i have installed carbonite over my rising goods wow (https://addons.rising-gods.de/addons/carbonite) but it is working quite grate but i have one porblem. My complete wow client is english which has the reason that i cant set locals and keyboard layouts seperately and i need the extra keys behind the 0 (- and =) on my international keyboard that i am used to. Otherwise i would use german settings.

The problem is now just that carbonite gives me any distances in yards but i would like to have them in meters. In questhelper i was able to switch them to metrical units by using the command

/qh metric

but i cant find a way to do the same with carbonite. Please help me out on this.

Thanks a lot

Aaron
