Even though I was good, not great!, in chemistry and physics class back in High School, it's been such a long time that I don't see what the benefits could possibly be to phase out the Calorie?
I wonder, given your obviously extensive back ground in both fields, which system is easier to work with? The Imperial or Metric?
I'm asking out of sheer curiosity because I grew up on the Metric and had to basically start from the ground up with the Imperial, which is still confusing to me. I still can't picture how big a 5/8" hole is, or a shaftlength of 8/16" on a quartz clock movement. But if you'd say i.e. the hole's gonna be 1.6 cm, I'd know.
