Absolutely! internalizing dimensional analysis has been one of the most useful things I learned in grad school -- even though converting units was something many of us learn, in one form or another, before college.
- lmilcin 6y agoIt is interesting how some of the things just feel like common knowledge when they are not. I frequently see people comparing things that aren't really comparable and it always seems to me it should be obvious this can't be done. Most common example is mixing watts and watt*hours. Which should be pretty obvious. Nobody mixes by accident the speed at which you travel with the distance you have to travel. Nobody says "My car can pull off 200kms" or "I have 120km/h to cover" yet the same happens for energy vs power on a daily basis, even in publications.
