For me, I find it easier to not try to translate, but use the metric
values as they are. Instead of thinking 10mm is .3937 inches, I think,
10mm is about the width of my pinky fingernail or the wrench size for
most of the bolts on my motorcycle. As time goes on, now that I am using
metric a lot more, I'm finding I'm getting a feel for the size without
the reference cues.
