If you're cutting blocks, concrete, stone or
ANYTHING
and there's
DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's
NO DUST
-
Silicosis Sucks
And if you're cutting wet, wear a mask - there's dust in the spray mist too!

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"
Although diameter and perimeter as measurements - don't seem to fit very well
If the U.S. 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
to Mars, this time, let's go Metric, ay?)
GO Artemis II !! (thats 2, not eleven - and Artemis is Metric, not Imperial, no matter what they say)
