If you're cutting blocks, concrete, stone or
ANYTHING

Don't cut it, or cut it wet so there's
NO DUST

What do we think? - They're 2 different things:
A
Meter
is a device to measure things - like a Volt Meter or a Parking Meter
A
Metre
is about 3'-3~3/8"

If the US ever goes Metric, you'll be able to use a Meter to measure Meters - A Meter Meter
(And when we go back to the moon, let's go Metric, ay?)
