PREFIX SYMBOL
for
EVERYDAY USE

m  milli is 1 one thousandth (0.001)
c  centi  is 1 one hundredth (0.01)
k  kilo is 1000 times as much


WRITING IS EASY

Simply place the prefix in front of the
base or derived unit
like mm (millimeter), cm (centimeter),
km (kilometer) or mg (milligram) kg (kilogram)
or mL (milliliter) for example.

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.

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 (C), Pascal (P) or
Newton (N). Then the symbol is noted by a CAPITAL LETTER.

What's with a capital letter "L" for liter when the capital letter is supposed to be for a persons name?

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".
