Voltage Converter

Convert between peak-to-peak, peak, and RMS voltage for a sine wave. Enter any value and the others will update automatically.

Vpp (peak-to-peak): V
Vpeak (peak): V
Vrms (RMS): V

Hover over labels for explanations.

Formulas (sine wave)

Vpeak = Vpp / 2

Vrms = Vpeak / √2 ≈ Vpeak × 0.707

Vrms = Vpp / (2√2) ≈ Vpp × 0.354
