Example of VA to Watts Calculations

To convert volt-amperes (VA) to watts (W), you need to know the power factor (PF) of the load. The formula to convert VA to watts is:

Watts=VA×Power Factor

Assuming a common power factor of 0.8 for these calculations.

Below is a table showing the conversion of various VA values to watts, sorted from smallest to largest, assuming a power factor of 0.8.

VA	Power Factor (PF)	Watts (W)	VA	Power Factor (PF)	Watts (W)
40	0.8	32	100	0.8	80
300	0.8	240	400	0.8	320
425	0.8	340	450	0.8	360
500	0.8	400	600	0.8	480
650	0.8	520	750	0.8	600
850	0.8	680	900	0.8	720
950	0.8	760	1000	0.8	800
1100	0.8	880	1200	0.8	960
1350	0.8	1080	1400	0.8	1120
1500	0.8	1200	1800	0.8	1440
2000	0.8	1600	2200	0.8	1760
3000	0.8	2400

To convert 500 VA to watts at a power factor of 0.8:

Watts=500×0.8=400 W

To convert 1000 VA to watts at a power factor of 0.8:

Watts=1000×0.8=800 W

To convert 1500 VA to watts at a power factor of 0.8:

Watts=1500×0.8=1200 W
