Metric Prefixes
Metric prefixes are symbols that represent the most commonly used powers
of ten in engineering notation. A metric prefix can replace the powers of ten
that is expressed in engineering notations. For example, 0.075 amperes
can be expressed as 75 mA. Or 100,000,000 ohms can be expressed as
100MΩ, the prefix mega has replaced the powers of ten value. See the chart
below for commonly metric prefixes with their symbols and corresponding
powers of ten values.

Metric Unit Conversions
It is often necessary to convert a quantity from one metric prefix unit to
another. An example of such an instance would be milliamperes (mA) to
microamperes(µA). When converting from a larger unit move the decimal
point to the right. When converting from a smaller unit move the decimal
point to the right. Determine the number of places the decimal point is
moved by finding the difference in the powers of ten.
