I well realize that now. Many of us worked with metric in the sciences for our university career, as well as prior high/middle/ele school teachings of metrication. Some of the lesser known units of imperial measure throw us off. I asked him to please explain this unfamiliar unit to us. He was rather surprised we hadn't heard of it prior. One very good thing about metric is that it is precise in the definitions of the units. Hence the distinction between kg and N. Added note: even though pound may be technically a force measurement, it at first confused the hell out of me how a pascal( N/m^2) could be converted to lbs/in^2. I did wonder what exactly a pound was, but soon didn't really care. After all, we didn't really use imperial much, with exception of general "consumer measurements".
