RMS to Peak Voltage Converter
Convert RMS voltage to peak voltage, peak-to-peak voltage, and average voltage for different AC waveform types.
โก RMS to Peak Voltage Converter โ Accurate AC Voltage Conversions Made Easy
When working with AC (Alternating Current) circuits, understanding the relationship between RMS Voltage and Peak Voltage is essential. Many devices, tools, and circuits use RMS values, but oscilloscopes and waveform generators often display peak values. Converting between these two is a common task in electrical engineering, audio systems, and power electronics.
Our RMS to Peak Voltage Converter tool makes this conversion fast, simple, and error-free. In this article, we'll explain what RMS voltage is, why it's important, the formula for converting it to peak voltage, and walk through some real-life examples.
๐ง What Is RMS Voltage?
RMS stands for Root Mean Square, and it's a way of expressing the effective voltage of an AC signal.
For a pure sine wave, RMS represents the equivalent DC voltage that would deliver the same amount of power to a load.
For example, a 120V RMS household supply in the US is equivalent, in power terms, to a 120V DC supply โ even though the actual voltage is swinging between +170V and -170V peak.
Where:
- ๐RMS = Root Mean Square Voltage
- ๐peak = Peak Voltage of the waveform
To find the peak voltage from RMS, we simply reverse this formula.
โ๏ธ RMS to Peak Voltage Conversion Formula
For a sine wave:
Where:
- ๐peak = Peak voltage
- ๐RMS = RMS voltage
This formula allows you to find the maximum amplitude of the waveform when you only know the RMS value.
๐ก Example 1: Converting 120V RMS to Peak
โ Result: A 120V RMS signal corresponds to a 170V peak sine wave.
This is exactly what you'll find in a standard household AC supply in many countries.
๐ก Example 2: Converting 35V RMS to Peak
โ Result: A 35V RMS signal has a peak voltage of approximately 49.5V.

โ ๏ธ Why RMS to Peak Conversion Is Important
- โ For Oscilloscope Measurements: Oscilloscopes often display peak or peak-to-peak values, while your circuit might be rated in RMS.
- โ For Power Calculations: Many power equations use RMS, but certain waveforms require peak values.
- โ For Component Selection: Capacitors, diodes, and other components must withstand peak voltages โ not just RMS.
- โ For Audio & Signal Processing: Audio engineers frequently switch between RMS (perceived loudness) and peak (actual signal spikes) levels.
โ Frequently Asked Questions (FAQ)
Q1: Why is peak voltage higher than RMS voltage?
A: Because RMS represents the effective power, not the waveform's highest point. For a sine wave, peak is always โ2 times higher.
Q2: Can this converter work for non-sine waveforms?
A: This calculator is designed for pure sine waves. For square or triangular waves, different conversion factors apply.
Q3: Why is my oscilloscope showing 170V when the outlet is 120V?
A: Because the oscilloscope displays peak voltage. 120V RMS ร โ2 โ 170V peak.
Q4: What about peak-to-peak voltage?
A: Peak-to-peak voltage is twice the peak voltage. So for 120V RMS:
