RMS Voltage Calculator
Convert peak voltage to RMS and average values.
RMS voltage is the effective DC-equivalent value of an AC sine wave.
The math behind it
For a sine wave, V_rms = V_peak ÷ √2 ≈ 0.707·V_peak; the rectified average is 2V_peak/π.
Worked example
325 V peak → 230 V RMS (European mains).
FAQ
Why use RMS?
It gives the same heating effect as an equivalent DC voltage.
