What does volt ampere (V*A) measure?

Volt ampere is a unit of apparent power in AC circuits, calculated as the product of RMS voltage and RMS current, regardless of the phase angle.

Is horsepower an SI unit?

No, horsepower is a non-SI unit commonly used to express mechanical power output, defined here as 550 foot-pounds per second or approximately 745.7 watts.

Why might VA not equal horsepower directly?

Because volt ampere represents apparent power, it differs from real power depending on the power factor, while horsepower measures actual mechanical power output.
