Watts to VA Calculator
Calculate the apparent power in Volt-Amps needed to supply a specific wattage.
VA = Watts ÷ Power Factor
800W ÷ 0.8 PF = 1000 VA
How do I convert watts to VA?
To convert watts (real power) to volt-amps (apparent power), you divide the wattage by the power factor of the circuit. Formula: VA = Watts ÷ Power Factor.
What is the difference between Watts and VA?
Watts measure "real power" (the actual energy performing work), while VA (Volt-Amperes) measures "apparent power" (the total power supplied to the circuit, including reactive power).
What is a typical Power Factor?
For a purely resistive load (like a heater), the power factor is 1.0. For most electronic equipment or motors, it typically ranges between 0.6 and 0.9.
