Conversion using the KW to KVA Formula

KW to KVA Calculation formula

The Apparent Power S in kilovolt-amps KVA is calculated as the Real Power P in Kilowatts kw, divided by the Power factor in pf. Plug these values into the formula:

For Example, let's find the apparent power in kVA for a 25 kW electric motor with a power factor of 0.8

How to use KW to KVA Calculator?

To use the above "KW to KVA Conversion Calculator" follow the below steps:

1. Enter Real Power: Input the Real Power in Kilowatts or Load Kilowatts value in the specific input box. You can enter the value in millivolts mw, Watts W, kilowatts Kw, & Megawatts MW by choosing the appropriate option from the dropdown.

Frequently Asked Questions - FAQs for Kw to KVA Calculator

What kW means?

KW is the abbreviation of kilowatt. In other words, it represents 1000W. It is the measure of Real power that is often converted into the form of usable output.

Is kVA higher than kW?

kW is the unit of real power and kVA is a unit of apparent power (or real power plus re-active power).

How many kW is a kVA?

The kilovolt-ampere (kVA) is the power rating of a circuit conveying 1,000V and an ampere or 1,000A and a volt. A single kilovolt-ampere is comparable to a kilowatt.

How many kVA is 2 ton AC?

As far as I know for a 2-ton inverter AC a 3.5 to 4 KVA stabilizer of 2533 watts is perfect. Let me tell you about four of the best AC stabilizers that you can buy for your AC.

What is 3.5 kW mean?

So a 3.5 kW appliance means an appliance that consumes 2.5kW of energy if it runs for 1 hour.
