When I design my own projects, I use metric. In my job all the data are in
feet and deg/min/sec. I can add feet, I can add meters, and I can add angles.
But errors are more likely when:
*I add angles, because I can't easily cast out 59.
*A house plan is drawn in feet, inches, and binary fractions, and I have to
convert it to decimal. I have typed 9.8 for 9 feet 8 inches, the house was
off by 0.1333 in one direction, and I had to search for the error.
If someone brought in a house plan in meters and the lot was drawn in feet,
I'd draw it and scale it by 1200/3937 (we use the survey foot).
