PMPO to Watts Calculator

Formula

The formula to convert PMPO to Watts (RMS) is:

$\text{Watts (RMS)} = \frac{\text{PMPO} \times \left(\frac{\text{Efficiency}}{100}\right)}{8}$

Where:

PMPO: Peak Music Power Output, the maximum power an audio device can output in short bursts.
Efficiency: The efficiency of the audio system, expressed as a percentage.
Watts (RMS): Real Mean Square power, a realistic measure of continuous power output.

Let's say the PMPO is 800 and the efficiency is 50%. Using the formula:

$\text{Watts (RMS)} = \frac{800 \times \left(\frac{50}{100}\right)}{8} = 50$

So, the Watts (RMS) is 50.
