rms stands for root mean squared. rms voltage is a way of measuring a sort of average alterating current voltage as distinguished from peak-to-peak voltage. Likewise for ac rms current.

The RMS value is equivalent to the average power delivered by a sinusoidal waveform. Therefore, 20 watts RMS is equal to the same amount of power in watts.
Yes, a voltmeter typically reads the root mean square (rms) value of the voltage in an AC circuit. This is because the rms value represents the effective value of an AC signal.
The ten most famous ocean liners of the 20th century include the following: the RMS Queen Mary II, the SS Rex, the SS France/SS Norway, the SS Bremen, the RMS Mauretania, the SS United States, the RMS Olympic, and the RMS Queen Elizabeth II.
"Watts RMS" is better represented as "Watts average". Since 1000 watts is 1kw you have "1000 watts average" and you can derive "1Kw average". So 1000 watts RMS will consume 1 Kw
RMS (Root Mean Square) value for power is equivalent to the average power output. Therefore, if a device has a power rating of 1200W RMS, it will output an average power of 1200 watts.
