Watts (W) to VA Conversion Calculator


Calculation used:


  1. Enter Watts:
    • In the input field labeled “Enter Watts,” input the amount of power in watts that you want to convert to VA (volt-amperes).
  2. Enter Power Factor:
    • In the input field labeled “Enter Power Factor (0-1),” input the power factor associated with the electrical device or system. The power factor typically ranges from 0 to 1, where 1 represents a perfect unity power factor.
  3. Calculate:
    • Click the “Calculate” button to compute the VA (volt-amperes) based on the entered watts and power factor.
  4. Result:
    • The calculated VA (volt-amperes) will be displayed below the calculator after clicking the “Calculate” button.
  5. Reset:
    • To clear the input fields and the result, click the “Reset” button.

If you encounter any issues or have further questions, please consult additional resources or seek expert advice.

Formula Used:

The formula used to calculate VA (volt-amperes) from watts and power factor is:

VA =     Watts    
     Power Factor


  • Watts is the amount of power in watts.
  • Power Factor is the ratio of real power to apparent power, typically ranging from 0 to 1.

This calculation helps in determining the apparent power required for an electrical system or device, considering the power factor which accounts for the effects of reactive power.
