### Vmax to Vrms conversion

Vmax of a sine wave voltage waveform is defined as the Positive Amplitudes on the sine wave.

The Vrms is defined as square root of the mean of the squares of the values for the one time period of the sine wave.

Following is the formula for Vmax to Vrms conversion.

V

_{rms}= 0.707 * V

_{max}

Where V

_{pp}is the max volatge and V

_{rms}is the root mean square voltage. To Calculate V

_{rms}from V

_{max}enter the value in V

_{max}and hit V

_{rms}button.

To Calculate V

_{max}from V

_{rms}enter the value in V

_{rms}and hit V

_{max}button.

We have a blog post that talks about the philosphy behind the existence of the V

_{rms}- check it out here.

We strongly suggest that you go through the following video to understand the relationship of Vrms and Vmax.
