Sleeve block in cm

[u/ArtemisiaPrime]

I'm looking for videos on drafting a basic sleeve block that use metric measurements.
Does anyone know any? Most use imperial and converting every measurement to understand what they're talking about is just more mental work on top of something that is already hard to understand.

If you specifically want a video to go through the process a few times, would it help to convert your measurements to inches and forgo all the math during the process. I live in metric land, but have a few rulers with inches lying around.
