Watts to Volts Converter

Use this tool to convert power (in watts or milliwatts) to voltage based on system impedance.

Ω
Result: 0 V

Conversion Formula:

V = √(W × Z)

Calculation Steps:

1. Multiply Watts by Impedance

2. Take Square Root

Common Reference Points:

Power Input Output Voltage
10 mW @ 50Ω 0.707 V
100 mW @ 50Ω 2.236 V
600 W @ 50Ω 173.21 V
1200 W @ 50Ω 244.95 V

This tool helps with:

  • Calculating voltage from power and impedance in electrical and RF systems.

  • Applying the formula V = √(W × Z)​ for quick conversions.

  • Verifying voltage levels for given power and impedance values.
