For the most part, our default is NAD83 US Feet. (the 1983 standard, really modern)

I work with feet, survey feet, meters, micrometers, kilometers, kilofeet, all in NAD27, WGS83, UTM N14W99, even ITRF2008 (find me THAT one!). When you are mapping 300-500 square miles, even the small difference between feet and survey feet crops up, and I need to use 5 or 6 decimals when converting between imperial and metric or things get sloppy.
