Average Voltage Calculator

The Average Voltage Calculator converts between the key voltage measurements of an AC sine wave — the average voltage that a rectified waveform produces over one half-cycle. Enter any one of Peak Voltage (Vp), Peak-to-Peak Voltage (Vpp), or RMS Voltage (Vrms), then select your voltage unit (mV, V, or kV) to get the Average Voltage (Vavg) along with all three remaining voltage values calculated simultaneously. Also try the kVA to Amps Calculator.

Frequently Asked Questions

How to calculate average voltage from peak voltage?

Average voltage is calculated from peak voltage using the formula: Vavg = (2/π) × Vp ≈ 0.637 × Vp. This formula applies to sinusoidal AC waveforms. See also our Watts to dBm Calculator.

What is the difference between average voltage and RMS voltage?

Average voltage is the mathematical mean of the rectified waveform over one period, while RMS voltage represents the equivalent DC voltage that would produce the same power in a resistive load.

Why is average voltage also called rectified average voltage?

Average voltage is called rectified average because it's calculated using the absolute values of the voltage waveform, effectively 'rectifying' the negative portions to positive values before averaging. You might also find our Volts to Amps Calculator useful.

What is the relationship between peak-to-peak and peak voltage?

For symmetric AC waveforms, peak voltage (Vp) is exactly half of the peak-to-peak voltage (Vpp). Therefore, Vp = Vpp/2 and Vpp = 2 × Vp.

Can this calculator be used for non-sinusoidal waveforms?

This calculator uses formulas specific to sinusoidal AC waveforms. For non-sinusoidal waveforms like square waves or triangle waves, different conversion factors would apply.

What voltage units are supported in this calculator?

The calculator supports millivolts (mV), volts (V), and kilovolts (kV). All conversions and results will be displayed in your selected unit.
