SI prefixes
The 20 SI prefixes used to form decimal multiples and submultiples of SI units are given in Table 5.

It is important to note that the kilogram is the only SI unit with a prefix as part of its name and symbol.
Because multiple prefixes may not be used, in the case of the kilogram the prefix names of Table 5 are
used with the unit name "gram" and the prefix symbols are used with the unit symbol "g." With this
exception, any SI prefix may be used with any SI unit, including the degree Celsius and its symbol °C.
Example 1: 10-6 kg = 1 mg (one milligram), but not 10-6 kg = 1 µkg (one microkilogram)
Example 2: Consider the height of the Washington Monument. We may write
hW = 169 000 mm = 16 900 cm = 169 m = 0.169 km using the millimeter (SI prefix milli,
symbol m), centimeter (SI prefix centi, symbol c), or kilometer (SI prefix kilo, symbol k).
