This tool converts kVA to watts to help you understand your electrical power usage.
How to Use the kVA to Watts Calculator
This kVA to Watts Calculator helps you convert kilovolt-amperes (kVA) to watts (W) using the power factor. Follow the steps below to use the calculator:
- Enter the value in kilovolt-amperes (kVA) into the “kVA” input field.
- Enter the power factor into the “Power Factor” field. This should be a value between 0 and 1. Power factor is a measure of how effectively the electrical power is being used.
- Click the “Calculate” button to obtain the result in watts.
Understanding the Calculation
The kVA (kilovolt-amperes) is a unit of apparent power, and watts (W) is a unit of real power. The conversion from kVA to watts requires you to know the power factor, which is the ratio of real power to apparent power. The formula used for the conversion is:
Watts (W) = kVA × 1000 × Power Factor
Limitations
The primary limitation of this calculator is the requirement for a known power factor. The power factor should be between 0 and 1. If you do not know the power factor, you will not be able to obtain an accurate result. Additionally, ensure all inputs are positive numbers.
