Converting Watts to KVA


KVA = (Watts / PowerFactor) / 1000
Where Power Factor is a number between 0 and 1.

Power Factor Examples
Light Bulb1
Switching Power Supply.85 to .92
AC Motor.7 to .86
These are approximate power factors and will very greatly depending on the device. Please consult the equipment manufacturer for the power factor or KVA of the unit.
