RMS Lusitania was a White Star ocean liner torpedoed and sunk by the German submarine U20 in 1915. Until then the US had remained neutral in World War 1, but as the Lusitania was a passenger ship, with its passengers including Americans, the sinking eventually led to the US entering the war on the Allied side in 1917.

rms is the best because 1 RMS = 100 PMPO
The sinking of the luistania angered Americans and congress declared war on the centeral powers
The RMS on Titanic stood for "Royal Mail Ship".
There is no proper formula to convert RMS to PMPO, but based on various observations it has been found out that 12W to 16W PMPO = 1W RMS.

RMS watts is not a real measurement. The correct measurement is "average power", which is measured in "watts". It is dervied from RMS voltage, but that doesn't make it "RMS watts". "RMS watts" would be 22% higher than the correct "average watts".
There is such a thing as "RMS power", but it's not useful for anything, so don't use the term. No one measures the RMS of the power waveform. What they do is measure the RMS of a voltage waveform, and then use that to derive the averagepower. The correct term is "average power", not "RMS power". You could measure the RMS of the power waveform instead of the average, but your measurement would be 1.2 times too high.
The RMS Olympic was indeed a real ship. It was the sister ship to the RMS Titanic. It was retired in 1935.
