Convert Volt-Amps (VA) to Watts (W)
To convert VA to Watts , Please provide the values below:
To calculate volt-amps to watts , use the following formula:
The Real Power in Wattsis equal to the Apparent Power in Volt-amps multiplied by the Power factor (pf)
For example,
If an Induction motor takes 1000va power at 0.95 (lag) power factor from the AC source. Calculate the Watts rating of the motor.
Answer
Where,
Apparent power S = 1000VA , Pf = 0.95
P w = S (VA) x Pf
P w = 1000 x 0.95
P w = 950
P = 950w

Frequently Asked Questions:
What is the formula for VA to watts ?
Use the following formula to calculate VA to watts : Real Power in Watts = Apparent Power(VA) x Power factor in PF.
What is DC Circuit 1000 volt-amps (VA) in watts ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 1000 va is the equivalent of 1000 watts.
What is AC Circuit 100 watts in volt-amps (VA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 100 watts is the equivalent of 117.65 VA. This equivalence means that the power factor of that power supply is 0.85.
What is the formula for watts to volt-amps ?
Apparent Power(VA) = Real Power(Watts) / Power factor in PF.
