RMS is not a unit of measurement!

[QUOTE="hispls, post: 8264934, member: 614752"] It's pure ignorance and looks ignorant when people write it. People who use the term think that an RMS is something that should be compared to some "peak" number which is and has always been pure marketing ******** and was never actually the peak to peak of the waveform, but simply a wishful thinking number that you may or may not be able to measure for one second before you see smoke. So you're saying I should just go ahead and let people be ignorant and act stupid instead of starting this thread to try to inform people? So if you're current is 10A RMS and your voltage is 10V RMS, your power would be 100W RMS^2? If the RMS is a unit of measurement it would need to be also multiplied. There is a large difference between a method of measurement and a unit of measurement and since the accepted method to deal with sine waves is the root mean square, writing RMS is redundant, and not necessary. I'm glad someone actually paid attention in school. Personally I'll let dB slide on it's own since in the context here it's implied that it's referring to sound intensity. I think you mean the other way around. Agreed, and I'll take that a step farther and say I'd really like to see SPEAKER manufacturers add some time numbers as well. In both cases I think most people who purchase based solely on whoever puts the biggest number on the box would be rather shocked. [/QUOTE]
