Convert Kilovolt-Amps (VA) to Watts (W)
To convert KVA 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 1,
If an Induction motor takes 10 KVA power at 0.95 (lag) power factor from the AC source. Calculate the Watts rating of the motor.
Answer
Where,
Apparent power S = 10KVA , Pf = 0.95
We know,
P w = 1000 x S (VA) x Pf
P w = 1000 x 10 x 0.95
P w = 9500
P = 9500w
For example 2,
If an Induction motor takes 5 KVA power at 0.85 (lag) power factor from the AC source. Calculate the Watts rating of the motor.
Answer
Where,
Apparent power S = 5KVA , Pf = 0.85
We know,
P w = 1000 x S (VA) x Pf
P w = 1000 x 5 x 0.85
P w = 4250
P = 4250w

Frequently Asked Questions:
What is the formula for KVA to watts ?
Use the following formula to calculate KVA to watts : Real Power in Watts = 1000 x Apparent Power(KVA) x Power factor in PF.
What is DC Circuit 1 Kilovolt-Amps (KVA) in watts ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 1 kva is the equivalent of 1000 watts.
What is AC Circuit 10 kva in Watts (W) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 10kva is the equivalent of 8500 watt. This equivalence means that the power factor of that power supply is 0.85.
What is the formula for watts to volt-amps ?
Real Power(Watts) = 1000 x Apparent Power(KVA) / Power factor in PF.
