Symbols like mL or mg
or mm or kg or
cm together
identify Prefix and everyday unit of measure.
Symbols
identify prefix
and base or derived unit OR everyday unit of measure
together.
Simply
place the prefix in front of the base
or derived unit
like mm
(millimeter), cm (centimeter), km
(kilometer)
or mg (milligram),
kg (kilogram) and mL
(milliliter).
The size or quantity is indicated by the first letter
or prefix symbol and the second letter or symbol identifies
the
base or derived unit. Please Note: Where
symbols
are used convention has it that they are
always lower case letters except where the
Base Unit is named after a person like Celsius (ฐC), Pascal (P) or
Newton (N).
Then the symbol is noted by a CAPITAL LETTER.
"So what's with a capital letter L for liter?
Is that a capital "L" for the unit of measure named
after a person?" No....
You see, when decimal
dimensions were described long before the typewriter you would have to
write the script.
But
as technology came along it became apparent that typewriters were not
equipped with the script
so attempts were made to use the lower case "l" (el).
Then it became further confusing to write "1l"
(lower case
"el") as the "1" and "l" (el)
looked
too similar as did the capital "I" (eye).
So the
capital "L"
was chosen as the symbol
for
the derived base unit "liter".
