THE reason why we-the us - is not on metric, if i remember correctly is,, reagan scrapped the program in the 80's.
personally, doesn't matter to me which we use, at work, i could use either- as an aside, ALL US DOT(department of transportation) plans HAVE to be done in metric.
is one more accurate? nope. they are about the same
at work i use Decimal feet 1'=10 tenths, 1 tenth has 10 hundredths, one hundred has 10 thousandths
at times i have to convert us inch feet to us decimal feet, or convert metric to decimal feet or hell i still come across work in chains, rods &links..
for the record a rod is 16.5 feet a link is 7.92 inches a chain is 66' and i still find roads laid out in those dimensionings in width
16.5 foot wide lanes/alleys
33 foot wide roads
66 foot wide roads
49.5 foot wide roads (these are a bitch because half the time the proper research is not done and someone fucks it up and calls it 50' wide on a plan of record,,which is wrong)
also occasionally i see 99' wide roads (chain and 2 rods width)
