I have edited my last post to reflect hand-written usage. Please go through again and tell me if I am still wrong.
As for why metric matters, I am simply much more familiar with the mass/weight units in metric. I couldn't even tell you what the units for slugs (the English system version of kilograms) are.

Hah, thats what we get for being lazy and not finding "μ" symbol, what you wrote looks close for the fan. But who knows what the usefulness will be, with all those extra variables. Most of that is going to be rough math + lots of test. I am excited for all the physics this year. If nothing else all that we wrote should help others later.
