Where P= KW

Answer / prakashchandra rana

kw= root 3*v*i*pf
kva= root 3*v*i
so the differnce between kw and kva is pf.

Answer / p.gupta.1852

kVA means kilovoltampear. It is a power of transformer
having zeero power factor whereas kw is stands for kilowatt
and it a power of load having power factor whether legging
or leading.
