This note helps explain the differences between Watts and VA and explains how the terms are correctly and incorrectly used in specifying power protection equipment. Many people are confused about the distinction between the Watt and Volt-Amp (V-A) measures for UPS load sizing. Many manufacturers ...
The power drawn by computing equipment is expressed in Watts or Volt-Amps (VA). The power in Watts is the real power drawn by the equipment. Volt-Amps is called the "apparent power" and is the product of the voltage applied to the equipment times the current drawn by the equipment. Bot...
amps (A) = watts (W) / volts (V) Volts to electron-volts conversion The energy in electronvolts (eV) is equal to the potential difference or voltage in volts (V) times the electric charge in electron charges (e): electronvolts (eV) = volts (V) × electron-charge (e) ...
the real power is equal to the apparent power. However, as waves of current and voltage coincide less, less real power is transferred, even though the circuit is still carrying current. Differences between real and apparent power, and thus watts and volt amps, arise because of inefficiencies ...
The formula to convert kilowatts to volt-amps is: S(VA)=1,000 × P(kW)/PF Thus, the apparent powerSin volt-amps is equal to 1,000 times the real powerPin kilowatts, divided by the power factorPF. You might also be interested in ourVA to kW calculator. ...
