Convert milliwatt to volt ampere
Please provide values below to convert milliwatt [mW] to volt ampere [V*A], or Convert volt ampere to milliwatt.
How to Convert Milliwatt to Volt Ampere
1 mW = 0.001 V*A
Example: convert 15 mW to V*A:
15 mW = 15 × 0.001 V*A = 0.015 V*A

Milliwatt
A milliwatt (mW) is a unit of power equal to one thousandth of a watt, used to measure small amounts of power.
History/Origin
The milliwatt was introduced as part of the metric system to provide a convenient unit for measuring low power levels, especially in electronics and telecommunications, with its usage expanding alongside the adoption of the watt as the standard power unit.
Current Use
Milliwatts are commonly used today in electronics, audio equipment, and wireless communication devices to specify power levels, such as in battery-powered devices, LED brightness, and signal transmission power.
Volt Ampere
Volt ampere (V·A) is a unit of apparent power in an electrical circuit, representing the product of voltage and current without considering power factor.
History/Origin
The volt ampere was established as a unit of apparent power with the development of electrical engineering, particularly as a measure in alternating current (AC) systems. It is derived from the SI units volt (V) and ampere (A).
Current Use
Volt ampere is used to quantify apparent power in AC electrical systems, especially in the context of transformers, generators, and power supplies, to assess capacity and performance.
