So 5000 VA is equivalent to 4 kW with a power factor of 0.8. Volt, Amps, Amp-hour, Watt and Watt-hour: terminology and guide Volt or Voltage (V): Current Ampere (A): Power Watts (W): : Capacity Amp hours (Ah). To convert VA to kW, we simply divide the VA by 1000 and multiply by the power factor (0.8). In other words, 1 watt is 3.62831E+52 times smaller than a. Enter apparent power in volt-amps and power factor and press the Calculate button to get the real power in watts: Enter. The volt ampere VA to watt W conversion table and conversion steps are also. The formula used in watts to planck powers conversion is 1 Watt 2.75610408151453E-53 Planck Power. This table assumes a power factor of 0.8, which means that the actual power delivered is 80% of the apparent power (VA). Instant free online tool for volt ampere to watt conversion or vice versa. P (kW) = 600 VA × 0.85 / 1,000 = 0.51 kW Volt-Amps to Kilowatts Conversion Table For old computers it used to be 0.6-0.65. Unfortunately, PF value is practically never stated in appliances spec sheet. VA to Watt conversion chart: In below table, you can find out the standard VA rating of the motor and their real power at different power factor. Hence at unity power factor, the real power is equal to the apparent power. Likewise, you can convert watt to VA by using this formula: VAW/PF. Calculate the real power in Watt supply through the alternator. For Example, If the apparent power in volt amps is 14 VA and the power factor is 0. It means that the real power in watts is calculated by multiplying the apparent power in volt amps by the power factor. The first step you need to consider is to enter the apparent power in Kilovolts-amps (kVA). Well, obviously you need to know the value of PF to do the calculation: WVA×PF, where PF is in decimal. The formula used in the conversion is P (W) S (VA) x PF. The real power P in kilowatts (kW) is equal to the apparent power S in volt-amps (VA), times the power factor PF divided by 1000:įor example, follow this example to convert 60 VA with a power factor of 0.85 to kilowatts. It is a conversion calculator which converts the apparent power in Kilovolt-amps and the power factor to watts (W). Watts and Volt Amps Whats a KVA and How is it Calculated VA Voltage x Amps Watts Voltage (root-mean-squared) x Amps (root-mean-squared) x Power Factor. if the cos(\$\phi\$) = 0.9, effective power will be 270W.KW to VA calculator ► VA to kW Calculation The 300W PSU will consume 300 W of effective power, for the other PSU the apparent power is given, effective power for this PSU will be lower, e.g. The real power P in watts (W) is equal to the apparent power S in volt-amps (VA), multiplied by the power factor PF. For reactive (inductive/capacitive) loads however, voltage and current are not in phase, and you have to take this phase difference (phi) into account.Įffective power = Voltage \$\cdot\$ Current \$\cdot\$ cos(\$\phi\$), in WattĪpparent power = Voltage \$\cdot\$ Current, in VAĪpparent power is higher for non-resistive loads, but that's because it contains a part of blind power power the utility has to provide but also gets back during part of the cycle (in the graph the part where the power is negative, purple line under the X-axis).īecause they have to provide it, but can't invoice it (after all they get it back) the utilities are not too happy with reactive loads, and industries have to pay fines if their cos(\$\phi\$) becomes too low.
