Right, but I still use metric everyday on the job (mm, kg, Nm, etc. - no cm). I even have a metric tape measure in inch and mm, but no cm. And I never callout an M8x1.25 cap screw as an M0.8x0.125 cap screw. My socket wrench tools are in inch and mm too.
When needing a inch-to-metric conversion, the user is most likely from the US. So, all I'm saying is I'd rather see it as inch-to-mm.
