what is the difference between 2000 va and 2000 watts

VA is apparent power; W is real power. At unity power factor, 2,000 VA and 2,000 W are numerically the same in this tool; with reactive loads, real watts are lower than VA for the same current.

Detailed answer

Volt-amperes (VA) = voltage × current magnitude without accounting for phase. Watts account for power factor (cos φ for sinusoidal AC). UPS and transformer sizes are often given in VA; resistive heaters are ~1 W per VA. This converter assumes 1 VA = 1 W for numeric conversion between VA and watt units.

Relationship context

Sizing a UPS or generator requires VA for current limits; billing and heat output are closer to watts. Always read the equipment power factor when it matters.
