VRMS Formula
The following formula can be used to calculate the root mean square voltage of a sinusoidal periodic voltage.
VRMS = Vpeak * .7071
- Where VRMS is the root mean square voltage
- Vpeak is the peak voltage
To calculate RMS voltage (VRMS), multiply the peak voltage by a value of .7071.
VRMS Definition
VRMS stands for root mean square voltage and it is a measure of the average voltage of the root mean of a sine wave voltage.

FAQ
VRMS stands for root mean square voltage. It’s a measure of the peak voltage of a sinusoidal periodic voltage source times 1/sqrt(2) (aka root mean). It’s often described as the amount of AC power required to produce the same heat effect as DC power at the peak voltage.
