Milli, micro, nano and pico are all prefixes attached to farads to define their actual values. These prefixes are as follows:
- Pico = 1 trillionth
- Nano = 1 billionth
- Micro = 1 millionth
- Milli = 1 thousandth
These prefixes are very easily used. For instance, one milli-farad is one thousandth of a farad. This is a common metric system utilized in electronics to define values.
