Enter your RMS value into the calculator to determine the Peak value.

RMS to Peak Calculation Formula

The following formula is used to calculate the peak value from the RMS value. 

Peak Value = RMS Value * √2

Variables:

  • Peak Value is the maximum value of the waveform.
  • RMS Value is the root mean square value of the waveform.

To calculate the peak value, multiply the RMS value by the square root of 2.

What is RMS to Peak Calculation?

RMS to peak calculation refers to the process of converting the root mean square (RMS) value of a waveform to its peak value. This is important in various fields, such as electrical engineering and signal processing, where understanding the peak value of a signal is crucial for designing and analyzing systems.

How to Calculate Peak Value?

The following steps outline how to calculate the peak value using the given formula.

  1. First, determine your RMS value.
  2. Next, use the conversion factor, which is the square root of 2 (approximately 1.414).
  3. Use the formula from above: Peak Value = RMS Value * √2.
  4. Finally, calculate the peak value by plugging in the values.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

RMS Value = 70.7

FAQ

1. What is RMS value?

RMS (Root Mean Square) value is a statistical measure of the magnitude of a varying quantity. It is used especially in the context of alternating current (AC) voltage and current measurements.

2. How is peak value different from RMS value?

Peak value is the maximum value of a waveform, while RMS value is the effective value of the total waveform. Peak value is always higher than the RMS value for the same waveform.

3. How often should I use the RMS to Peak calculator?

It’s helpful to use the RMS to Peak calculator whenever you need to convert RMS values to peak values for accurate analysis and design purposes.
