Why are prefixes used in physics?
Prefixes are useful for expressing units of physical quantities that are either very big or very small. If you write out such big or small numbers, it will be time consuming and prone to errors.

When to use order of magnitude?
Order of magnitude is useful when you do “ back-of-the-envelope ” calculations. A back-of-the-envelope calculation is a rough calculation, typically jotted down on any available scrap of paper such as an envelope.
What is the SI unit in Table 5?
Table 5. SI prefixes. 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.".

What are the units used in physics?
The standard units we use in Physics and all over the world are the SI units, and these units are based on the metric system of units. We generally use these prefixes with units from the metric system and they are also called metric unit prefixes.
Is gg a SI unit?
But these prefixes are not only used with the SI units but can also be used with any other unit. Note that gram ( g g) is not the SI unit and we use these prefixes with gram not kilogram even if kilogram (it already has the prefix 'kilo') is the SI unit.
