its pretty standard for people to still use feet & inches for a person's height. if you notice when police are looking for someone, they will say 'a 6'3" male was spotted at..' its never 'a 190cm tall male was spotte at..'
also on all the banks, some supermarkets, most 24hr convenience stores etc, there are stickers on the door that are colour coded and are in 1 foot incrememnts. its there so the cashier that is being robbed can look at the person as they walk out the door and say 'yes the person was approximately xx feet & xx inches'
although, i saw one of those stickers on a door of a 7-11 the other day and it must have been put in a foot too low, cause it says i'm well over 6 foot, but i'm not.
