Centiwatt to Volt-Ampere Converter

A centiwatt (cW) is a unit of power equal to one hundredth of a watt (0.01 W). It represents extremely small power levels found in ultra-low-power electronics, precision sensors, and specialized instruments.

The centiwatt developed with the need for precise power measurements in advanced electronics and scientific instruments. It became important for describing power consumption in ultra-low-power devices and precision measurement systems.

Centiwatts are used in ultra-low-power electronics, precision sensors, and specialized scientific instruments. They're essential for describing power consumption in advanced sensors, precision circuits, and ultra-low-power electronic systems.

Volt-ampere (VA) is a unit of apparent power in AC electrical systems, representing the product of voltage and current. It differs from watts (real power) in AC systems where voltage and current may not be in phase.

Volt-ampere became important with the development of AC electrical systems, where the distinction between apparent power and real power became crucial. It provided a way to specify the total power capacity of AC electrical equipment regardless of power factor.

Volt-amperes are used for AC electrical equipment ratings, transformer specifications, and electrical system design. They're standard for UPS ratings, transformer capacity, and AC electrical equipment where apparent power is more relevant than real power.
