Size wise our projects are not so large so that may be why we all use mm. Probably someone designing a house (or a bridge or a city) would use some other unit. I don't think I have ever seen centimeters or meters used in our world even though injection molds can be several thousand in mm's.
The reason asking about the metric system, My new position at work will be involved in wiring electric panels for international customers that use the metric system.
Does it make a difference if we are talking measuring electric cable to length?
