The peak-to-peak amplitude of a sinusoid is the rms value multiplied by 2√2. For a sinusoidal voltage, V p-p = V rms × 2√2, where V p-p is the peak-to-peak voltage and V rms is the rms voltage.
What is the formula for peak-to-peak?
Peak-to-peak value is equal to two times the square root of two times VRMS, or roughly 2.8284 times VRMS.
How do I convert Vrms to VPP?
To compute VP-P from the RMS voltage, the RMS voltage is multiplied by 2.8284. To compute VP-P from the average voltage, the average voltage is multiplied by 3.14159. A user enters the voltage, V and the result will automatically be calculated and shown.
