This tool helps you easily convert RMS voltage to DC voltage.
VRMS to VDC Calculator
This calculator converts the Root Mean Square Voltage (Vrms) to Direct Current Voltage (Vdc) using the Crest Factor.
How to Use the Calculator
- Enter the Vrms value in volts.
- The Crest Factor is pre-set to 1.414, which is a common value for sinusoidal waveforms. You can adjust it as needed for different waveform shapes.
- Click the “Calculate” button to compute the Vdc value.
- The result will be displayed in volts (V) in the “Result” field.
How it Works
The calculator uses the following formula to convert Vrms to Vdc:
Vdc = Vrms × Crest Factor
The Crest Factor is a value that relates the peak value of a waveform to its Root Mean Square (RMS) value. For a pure sinusoidal waveform, the Crest Factor is approximately 1.414, but it can vary for other types of waveforms.
Limitations
- The accuracy of the Vdc value is dependent on the accuracy of the input Vrms value and the appropriate Crest Factor for the waveform in question.
- The default Crest Factor of 1.414 is suitable for sinusoidal waveforms, but may not be accurate for other waveform types.
- Ensure that the input values are numerical and valid to avoid calculation errors.
