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.**
