Most often measurements made on electric circuits are that of current, voltage, resistance, and power. The base units—ampere, volt, ohm, and watts—are the values most commonly used to measure them. Table 1 lists these basic electrical quantities and the symbols that identify them.

When moving down a prefix, let's say from nano- to pico-, the decimal place is moved three places to the right. 1 nanoFarad equals 1000 picoFarads. .5 nanoFarad equals 500 picoFarads. Here's a short list so you can see the pattern:
The standard electrical units of measure used for the expression of voltage, current and resistance are the Volt [ V ], Ampere [ A ] and Ohm [ Ω ] respectively. These electrical units of measurement are based on the International (metric) System, also known as the SI System with other commonly used electrical units being derived from SI base ...

The decimal sign The IEC and the BSI indicate that a comma on the line is the preferred decimal sign. In most British Standards, most UK literature, and all USA literature it is the practice to use a dot on the line as the decimal marker. In order to avoid confusion the IEE
All the units used to describe electrical quantities are part of the metric system. In the US, we use a measuring system known as the US Customary System for many physical quantities, such as distance, weight and volume. In this system there is no logical progression between the various units.
To convert a number represented by scientific notation to a decimal number, we would simply move the decimal to the right the number of places indicated by the exponent. Example. Let’s take the following number and convert it to scientific notation: 2,500,000 Our number.
