we use the base 10
all our high tech engineering is SAE (and other English and American units of various types) utilizing decimals.
I was referring to things like (1 mile = 5280 ft = 1760 yards) vs. ( 1 kilometer = 1000 meters)
I didn’t mean base 10 vs. octal or binary or hexadecimal. I should have clarified that. My bad.
I just think it would we wise for everyone to use one system, even if it’s the English system.
