Section 2-1 Engineering Notation for Electronics
| Definition  Engineering notation is a special form of power-of-10 notation where - The coefficient must be between one and three digits (not including zero) to the left of the decimal point.
- The exponent must be 0 or any multiple of 3
And since this is a power-of-10 system of notation, the base is always 10. | | Name | Label | Power-of-10 | | kilovolt | kV | x 103 | | volt | V | x 100 | | millivolt | mV | x 10-3 | | microvolt | mV | x 10-6 | | Name | Label | Power-of-10 | | ampere (amp) | A | x 100 | | milliampere (milliamp) | mA | x 10-3 | | microampere (microamp) | mA | x 10-6 | | Name | Label | Power-of-10 | | megohm | MW | x 106 | | kilohm | kW | x 103 | | Ohm | W | x 100 | | Name | Label | Power-of-10 | | megawatts | MW | x 106 | | kilowatt | kW | x 103 | | Watt | W | x 100 | | milliwatt | mW | x 10-3 | | microwatt | mW | x 10-6 | Adding and Subtracting Electrical Quantities | Procedure Adding and Subtracting Electrical Quantities
