### Power Triangle

Enter your Watts and VARs and convert them to polar quantities. Or vice versa, enter your Volt-Amps and Angle and convert them to Watts and Vars. (Actually on this app you can enter any two of the four quantities and the calculated output is the remaining two un-entered quantities.) Volt-Amps = √((Watts*Watts)+(VARs*VARs)) and Load Angle = ArcTan(VARs/Watts).

Watts: VARs:

Volt-Amps: Load Angle: degrees
