RMS Voltage Calculator | Good Calculators
https://goodcalculators.com/rms-calculator/
Example of an RMS Voltage Calculation. Let's say a sinusoidal voltage has a maximum value of 200V and we want to determine its RMS value. We can do so as follows: V RMS = V pk / √2. V RMS = 0.7071 × 200V = 141.42V. You may also be interested in our Motor FLA Calculator or Transformer Calculator.

If this is meant as a method of measuring the rms value of a mains voltage then the accuracy of the result is really not great. This method relies on the quantity being sinusoidal and mains is typically quite distorted and if measured on the secondary of the average small power transformer it can have far worse distortion.
What Is RMS? -What Does RMS Power Rating Mean In Speakers?

What is RMS output? RMS (Root Mean Square) is the preferred method of obtaining power measurements for audio signals. The idea behind it is to give you an idea of how powerful your sound system will be perceived by the audience/listener. This means that the human ear perceives lower sound levels than what they are actually exposed to.

For example, two 8-ohm speakers in parallel have an impedance of 4 ohms. In that case, each speaker would receive half of the amplifier's 4-ohm power. Power Calculator. On the Crown website is a calculator that determines the amplifier power required to achieve the desired SPL at a certain distance.

P=V*I. V=I*R. Those are true for all electrical circuits. These are measurments on the outputs. For example an amp has an output voltage of 20 V and is driving a 4 ohm load. V/R=I so I=5A. P= (20V)* (5A)=100W. You can measure the output voltage with a multimeter.
