Conversion using the KVA to Watts Formula

KVA to Watts Calculation formula

The Real Power P in Watts w is calculated as the 1000 times the apparent power S in Kilovolt-amps KVA, times the power factor pf. Plug these values into the formula:

Real Power(p) = 1000 × Kilovolt-amps(s) × Power factor(pf)

or, P(W) = 1000 × S(KVA) × pf

or, watts = 1000 × KVA × pf

For Example, let's convert 16 kVA to watts using a power factor of 0.8.

Frequently Asked Questions - FAQs for KVA to Watts Calculator

How many watts is 10 kVA?

For a 10 KVA generator at unity power factor (1.0), the maximum output is 10000 watts (volts × amps × power factor ÷ 1000), but at 0.8 power factor (Some Crommelins generators) it will be 8000 watts.

What is the kW formula?

The conversion of watts to kilowatts is just as straightforward as you may have guessed. We find the Real power in kilowatts Power (kW) by dividing the Real power in watts Power (W) by 1,000.

What is kW size?

A kilowatt is a unit of power representing a rate of 1000 watts of electrical energy.

Is 3 kWh 3 unit?

3 unit of electricity = 3 kWh. The electricity used is generally charged for in unit of electricity'. Kilowatt-hours is the product of watts × time (1 kilowatt = 1000 watts).

How to calculate kVA?

To calculate the kVA rating for a single-phase transformer, you will need to multiply the required input voltage (V) by the required current load in amperes (l) and then divide that number by 1,000: V × l ÷ 1,000.
