1. What is a kVA to kW Calculator?

Definition: This calculator converts apparent power (kVA) to real power (kW) using the power factor.

Purpose: It helps electrical engineers, technicians, and facility managers determine the actual power consumption of electrical systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Real power (kilowatts)
• \( kVA \) — Apparent power (kilovolt-amperes)
• \( PF \) — Power factor (unitless, between 0 and 1)

Explanation: The apparent power is multiplied by the power factor to determine the actual usable power (kW) that performs work.

3. Importance of kVA to kW Conversion

Details: Proper conversion ensures accurate electrical system sizing, energy efficiency calculations, and correct utility billing.

4. Using the Calculator

Tips: Enter the apparent power in kVA and power factor (default 0.8). Power factor must be between 0 and 1.

5. Frequently Asked Questions (FAQ)

Q1: What is power factor?
A: Power factor is the ratio of real power (kW) to apparent power (kVA), representing the efficiency of power usage.

Q2: What's a typical power factor value?
A: Industrial facilities typically aim for 0.95+, while 0.8 is common for many electrical devices.

Q3: Why is kW less than kVA?
A: kW represents actual usable power, while kVA includes both usable power and reactive power that doesn't perform work.

Q4: How can I improve power factor?
A: Using power factor correction capacitors, minimizing idle motors, and selecting efficient equipment can improve PF.

Q5: When would I need this calculation?
A: When sizing generators, transformers, UPS systems, or calculating energy costs for inductive loads.
