Why we denote 2KVA in ups while 2WATT?

The term "2KVA" in a UPS (Uninterruptible Power Supply) refers to its apparent power capacity, measured in volt-amperes (VA), which encompasses both active power (watts) and reactive power. This measurement is crucial for understanding how much electrical power the UPS can handle, including the power factor. In contrast, "2Watt" is a measure of active power, which indicates the actual power consumed by devices. Thus, KVA accounts for the total power capacity, while watts denote the usable power.
