let other ppl define their standards and I use 'em. But
personally? I measure distances by what's around me; landmarks
and things. I measure cooking by sight or by certain caps of
bottles if I must measure and whatnot. I can extraordinarily
precise when I *must* measure using standard measurements and
honestly, i hate being excessively precise because it just takes
over.
I prefer rounding. Round up. Round down. More or less. Just
about. "Here, if you see this landmark, YOU'VE GONE TOO FAR" -
that sort of thing. Also, my SHOE happens to be _exactly_ one US
FOOT - which is EXTREMELY handy when I'm in them.
But if my foot wasn't, I'd still count feet by feet - *my feet*.
Someone else can go get a measuring tape if they want to.
