What is the difference between KVA and KW? !

Is KVA equal to KW? ! Is KVA more used for safety verification? !
In AC circuits, there are three concepts of electrical power: real power, reactive power, and apparent power. kVA represents apparent power, which includes reactive power and active power; kW represents active power, while kVar represents reactive power. There is another concept related to the relationship and conversion between kW and kVar – the power factor cosΦ. The active power is given by kW = UI cosΦ, the reactive power by kVar = UI sinΦ, while the apparent power is kVA = UI (where U is voltage and I is current).
The explanation on the 2nd floor is super clear: lol
