In each case, a well defined signal represents 0 dBFS. One scale is better for electrical measurement (the peak scale) while the other is better for acoustic measurements (the RMS scale). Programs like Audacity, Adobe Audition, and Room EQ Wizard, allow the user to select which reference they prefer. One is the peak value of a sine wave, and the other is the RMS value of a sine wave. An interesting caveat being a standard PPM (peak program meter) will show that a -20 dBFS sine wave will have peaks -20.on the other hand -20 dBFS pink noise will have relatively constant peaks at approximately -10 dBFS.On top of that, there's two references for 0 dBFS.
