Watts to VoltAmpere Calculator

How to Use the Calculator

1. Enter the real power in watts (W) in the first input field.
2. Enter the power factor (PF) in the second input field. The power factor is a dimensionless number between 0 and 1 that represents the ratio of real power to apparent power.
3. Click the "Calculate" button to compute the apparent power in volt-amperes (VA).
4. The result will be displayed in the third input field.
5. Click the "Reset" button to clear all input fields and start over.

Understanding the Formula

The apparent power (VA) is calculated using the formula:

VA = W / PF

Where:

• VA = Apparent Power (Volt-Ampere)
• W = Real Power (Watts)
• PF = Power Factor

Practical Applications

This calculator is useful for electrical engineers, technicians, and anyone working with electrical power systems. It helps in determining the apparent power required for a given real power and power factor, which is essential for proper sizing of electrical equipment and distribution systems.

Example

If a device consumes 500 watts (W) and has a power factor of 0.8, the apparent power (VA) can be calculated as:

VA = 500 W / 0.8 = 625 VA
