Millivolt-Ampere [mVA] to Kilovolt-Ampere [kVA] Converter

Definition: A millivolt-ampere (mVA) is a unit of measurement for apparent power, equal to one-thousandth of a VA (Volt-Ampere). It is used to quantify smaller amounts of apparent power in AC electrical circuits.

History/origin: The millivolt-ampere (mVA) is a derivative of the VA (Volt-Ampere). The 'milli-' prefix denotes a factor of 10^-3, making mVA suitable for measuring smaller apparent power quantities.

Current use: mVA are used in applications where precise measurement of small apparent power quantities is needed, such as in electronic circuits and small power electronic devices. They can also be used in detailed power system analysis and simulation studies.

Definition: A kilovolt-ampere (kVA) is a unit of measurement for apparent power, equal to 1000 VA (Volt-Amperes). Apparent power is the product of the root mean square (RMS) voltage and the RMS current.

History/origin: The kilovolt-ampere (kVA) is based on the concept of apparent power. The 'kilo-' prefix indicates a factor of 1000, making kVA a more convenient unit for larger apparent power quantities.

Current use: kVA are commonly used to measure and manage apparent power in industrial and commercial power systems. They are used in specifying the size of generators, transformers, and other electrical equipment, as well as in billing customers for electricity consumption.
