Unless I need
precision, I think of an inch as 25 mm
Same here. The
base is a 100 mm module, so an "inch" is OK slang for a 25 mm
subdivision. Much as a "quarter" is OK slang for a 25 cent piece out of a
100 cent dollar. It isn't elegant but it works, in a
reality of continued ifp.
Volume, a cup is 240 to
250 ml and a pint becomes 500 ml (or � liter in colloquial terms).
Also an "ounce" is something you
triple and add a zero to. Subtract 5% for grams, like figuring a
tip.
Interestingly, when
thinking of a mile as 1600 m, it gives the nice divisible numbers (400, 800,
1200) for �, � and � mile that you don’t get with dividing 5280
feet.
That's very useful, I'll remember
that.
Also, square feet to square meters:
knock off 8% and drop a zero.
Also:
Thermometer
reads:
Say:
-5 to
0
"little below freezing"
0 to
5
"little above freezing"
5 to
10 "forties"
10 to
15 "fifties"
15 to
20
"sixties"
etc,
etc
