How to Convert Watt Peak (Wp) to RMS (Wrms)
To convert RMS values to watts, you can use the following relationship:
Wp to Wrms Calculation Formula (Sinusoidal Waveform)
The relationship between watt peak (Wp) and RMS (Wrms) can be expressed as:
Wrms = Wp / √2or approximately:
Wrms ≈ Wp × 0.707Example Calculation
If you have a watt peak measurement of 100 Wp, the calculation would be:
Wrms = 100 Wp / √2 ≈ 70.71 WrmsWatt Peak (Wp)
Watt peak (Wp) represents the maximum power output of a device under ideal conditions.
RMS (Root Mean Square)
RMS is a statistical measure of the magnitude of a varying quantity and is used in electrical engineering to calculate effective values. For more information, visit this Cuemath page.
