DID
YOU KNOW?
that you can divide 1 meter
by exactly 10 equal parts
(10 cm x 10 cm x 10 cm)
then make
a cube (1000 cmณ)
of it to fill with
water
and you will find that it
contains
exactly 1 L (1 liter)
(1000 mL)
of water
and is the mass of exactly
1
kg (1 kilogram) (1000 g).

The International
System of Units is called "SI"
and is the Metric Measurement used in America.
PREFIXES
But for most everyday experience
Prefixes we use are
milli, centi,
kilo
NOTE:
There are no abbreviations in metric measurement,
only symbols to denote Quantity, Size or Value.
(Abbreviations are archaic and reserved
for
"Inch-Pound" measurement like "ft."
"in." "lb." etc.)
So how do we get "lb." for pound?
Who Cares...???
