To convert from RMS to peak voltage use `V_(rms)=(V_(peak)/sqrt2)`
Example: if you measure a voltage using oscilloscope to be 10vp to convert it, use the formuls `V_(rms)=(V_(peak)/sqrt2)` and sub in the values:
`V_(rms)=(10/sqrt2)=7.07V_(rms)`

To convert from Peak voltage to RMS use `V_(peak)=V_(rms)sqrt2`
Convert for example your home voltage you measured using a multimeter to be 120vrms, to peak voltage use the formula above `V_(peak)=V_(rms)sqrt2`and sub in the values:
`V_(peak)=120sqrt2=169Vp`



RMS mean Root mean square.
