AC Sine RMS Voltage to Peak Calculator

AC Sine RMS Voltage to Peak is intended for the specific electrical task described by its name. Enter sinusoidal rms voltage v to calculate a result expressed in V. The formula works entirely in your browser and needs no account or external API. Applies only to a sinusoidal waveform. This estimate is useful for comparing scenarios when the supplied measurements follow the stated assumptions.

How to use this calculator

  1. Measure sinusoidal rms voltage v in the units indicated on the input label.
  2. Review the input range and units before calculating.
  3. Read the V result, then compare alternative inputs to evaluate your own situation.

AC Sine RMS Voltage to Peak formula

rms*Math.sqrt(2) (V).

  • The expression rms*Math.sqrt(2) combines Sinusoidal RMS voltage V. Follow the units on each input: the answer is expressed in V.
  • Applies only to a sinusoidal waveform.

Worked examples

Worked example: AC Sine RMS Voltage to Peak

Use these sample measurements: Sinusoidal RMS voltage V = 120.

Compute rms*Math.sqrt(2).

Using the example inputs, the result is 169.7056 V. Use this value to verify the formula before changing the measurements.

Understanding the result

Interpret the output as V; it is not a measurement taken directly from a physical system.

Applies only to a sinusoidal waveform.

Important notes

Applies only to a sinusoidal waveform.

Review the input units, any required legal or engineering rules, and unusual edge cases before acting on this estimate.
