Question

How many units are in 1 kVA?

Answer 1

1 kVA (kilovolt-ampere) is equal to 1,000 VA (volt-amperes). To convert kVA to units of energy (kilowatt-hours, or kWh), you'd need to know the power factor (pf) of the system.

For a purely resistive load (like a heater), the power factor is 1, meaning:

- 1 kVA = 1 kW (kilowatt)

However, if the power factor is less than 1 (which it usually is for inductive or capacitive loads like motors), then:

- kW = kVA × Power Factor

For example, if the power factor is 0.8:

- 1 kVA = 0.8 kW

To get the number of units (kWh), you'd need to multiply the power (in kW) by the time (in hours) that the equipment runs.

So:

- 1 kVA = 1 kWh in 1 hour (if power factor is 1)
- If power factor is 0.8, then 1 kVA = 0.8 kWh in 1 hour

The exact number of units will depend on the load's power factor and usage time.
