How to convert Watts to VA in only 1 step.
Divide the W (Watts) between the power factor (F.P). See the common power factors on this website: https://www.calculatorsconversion.com/en/the-power-factor-values-%E2%80%8B%E2%80%8Bfor-the-most-common/.
Definition F.P, S (VA) and P (Watts):
Watts: is Working Power (also called Actual Power or Active Power or Real Power). It is the power that actually powers the equipment and performs useful work.
The real power in watts is the power that performs work or generates heat. Power in watts is the rate at which energy is consumed (or generated). One watt is one joule (energy) per second (1 W = 1 J/s).
Resistive devices or loads such as heaters, incandescent lamps are rated in W.
VA: A kilovolt-ampere, commonly referred to as a VA, is commonly used as a unit of power in obtaining the electrical capacity of circuit breakers, uninterrupted power supplies and wirings.
VA is larger than W because loads are inductive such as motors, discharge lighting, reactors and more current is required to keep the magnetic field energized than is -turned into heat (W).
Inductive devices or loads such,. as tansformers and motors having power factor less than 1.0 are generally rated in VA.
F.p: Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used. A high power factor signals efficient utilization of electrical power, while a low power factor indicates poor utilization of electrical power.
Power Factor is the cosine of the phase angle between current and voltage.
Power Factor is the ratio of true power to apparent power.
