Watt(W) is the SI unit of power equivalent to one joule per second.
While Root mean square (RMS watts) refers to continuous power handling of a speaker or a sub woofer or how much continuous power an amplifier can output.
Formula to convert W to RMS.
To convert W to RMS, you need to know the conversion ratio.
We say that 1 watt is equivalent to 0.707 RMS.
Therefore, to convert W to RMS watts, we multiply the Watts by 0.707.
RMS Watts = Watts x 0.707
Example:
Convert 50 watts to RMS watts.
= 50 x 0.707
= 35.35 RMS watts.
