What exactly does 3HP mean? I really doubt my 3HP shop vac motor could replace the motor on my 3HP unisaw. So what exactly is 3HP then?

Because in quantum computing the cat is within a special entanglement of qubits wherein the qubits are in an equal superposition of all being 0 and all being 1. However, in the physical world, there is no superposition, something is either a 1 or a zero. The cat is not both alive and dead (as a superposition posits).
I guess!

I learned a lot from this thread. Especially about why cats can sneak into a room. But mostly this
So, to answer your question….."3hp" is roughly 3 times more BS than 1hp……;-)
Or in other words "HP = horse poop" (after all it is what comes out at the other end of the motor that is most important consideration)

I kind of like what Joe Ryer did - he'd dial all but the last digit of a telephone number, then visualize himself inside the telephone line - hey man, like, I'm inside the wire - inside the wire! - then take another toke, just because he needed to take another toke - Like, I'm inside the wire, man!
Only John Galt could make a true 3HP machine!

3 hp requires 3 times a much smoke to operate as 1 hp. The reason they are calling puny motors 3 hp instead of 3/4 is they are blowing smoke up your…........
Proof is here:
Electrical Theory - by Joe Lucas
Positive ground (they meant "earth") depends on proper circuit functioning, which is the transmission of negative ions by retention of the visible spectral manifestation known as smoke.
Smoke is the thing that makes electrical circuits work. We know this to be true because every time one lets the smoke out of an electrical circuit, it stops working. This can be verified repeatedly through empirical testing.
For example, if one places a copper bar across the terminals of a battery, prodigious quantities of smoke are liberated and the battery shortly ceases to function. In addition, if one observes smoke escaping from an electrical component such as a Lucas voltage regulator, it will also be observed that the component no longer functions. The logic is elementary and inescapable!
The function of the wiring harness is to conduct the smoke from one device to another.
When the wiring springs a leak and lets all the smoke out of the system, nothing works afterward.
Starter motors were considered unsuitable for British motorcycles for some time largely because they consumed large quantities of smoke, requiring very unsightly large wires.
It has been reported that Lucas electrical components are possibly more prone to electrical leakage than their Bosch, Japanese or American counterparts. Experts point out that this is because Lucas is British, and all things British leak. British engines leak oil, British shock absorbers, hydraulic forks and disk brake systems leak fluid, British tires leak air and British Intelligence leaks national defense secrets.
Therefore, it follows that British electrical systems must leak smoke. Once again, the logic is clear and inescapable.
In conclusion, the basic concept of transmission of electrical energy in the form of smoke provides a logical explanation of the mysteries of electrical components especially British units manufactured by Joseph Lucas, Ltd.
And remember: A gentleman does not motor about after dark.
Joseph Lucas - The Prince of Darkness
A few Lucas quips:
The Lucas motto: Get home before dark.
Lucas is the patent holder for the short circuit.
Lucas - Inventor of the first intermittent wiper.
Lucas - Inventor of the self-dimming headlamp.
The three-position Lucas switch-DIM, FLICKER and OFF. The other three switch settings-SMOKE, SMOLDER and IGNITE.
The Original Anti-Theft Device - Lucas Electrics.
If Lucas made guns, wars would not start either.
Back in the '70s, Lucas decided to diversify its product line and began manufacturing vacuum cleaners. It was the only product they offered which did not suck.
Q: Why do the British drink warm beer?
A: Because Lucas makes their refrigerators.

One thing I learned from working in electronics is motor ratings are all BS (as most stated here). They are useful to compare within brand most of the time.
For example, a 3HP rigid shop vac is likely twice as powerful as a 1.5hp ridgid shop vac. Depending on how others rate their tools, you really cannot accurately compare across brands because there is no set standard unit of measurement.

I know I have my bottle of Lucas smoke here somewhere.
(They had to store it in glass because it leaked out of all the tins)!

Hilarious!
I was an automotive technician (what we used to call, variously mechanic or grease monkey) in what we used to call foreign car garages. That was in another life, many years ago.
We worked on every kind of English (British) car there was and the Lucas jokes abounded. The worst case of Lucas failure was the MG Midget (and it's illegitimate brother the Austin Healy Sprite) because when the headlights, radio and heater were on all at once, the draw was greater than the output of the little Lucas DC generator.
Oh, what fun that was, explaining to the folks who bought them that they shouldn't use them in the Winter!
By the bye, your collection of Lucas jokes is the best I have ever heard.

Calculating Horsepower:
Electrical power is rated in horsepower or watts. A horsepower is a unit of power equal to 746 watts or 33,0000 lb-ft per minute (550 lb-ft per second). A watt is a unit of measure equal to the power produced by a current of 1 amp across the potential difference of 1 volt. It is 1/746 of 1 horsepower. The watt is the base unit of electrical power. Motor power is rated in horsepower and watts.
Horsepower is used to measure the energy produced by an electric motor while doing work.
To calculate the horsepower of a motor when current and efficiency, and voltage are known, apply this formula:
HP = (V x I x Eff) /
746
HP = horsepower
V = voltage
I = curent (amps)
Eff. = efficiency

This post certainly took a few twists and turns. Anyone want to discuss "Commercial", "Industrial", and "Professional" - grade??? Seems to fit into the same general line of thinking/Marketing.

Yes, it has been a very informative thread so far.
We might as well add continuous, intermittent, compressor, refrigeration duty to the definitions also.
Also, Eff. and PF. are two different animals.

Commercial = you let your hourly employees destroy it. Industrial = you let your union employees destroy it (lasts longer because of mandatory breaks) Professional = you get to destroy it, until someone takes it out of your kit without asking.
8 tiny reindeer have the same power as one 2000 pound Percheron; therefore, 1 HP = .125 RDP or 93.25 watts. It is calculated by the formula RDP = I x E x efficiency x power factor/ 93.25.
I agree with the 8 tiny reindeer, but we have to remember, male reindeer drop their antlers every year. Only female reindeer retain their antlers.
How do we interpret that, since we all know that over the distance those eight tiny reindeer travel in a night, there are going to be at least 72 potty breaks! Maybe even more….. remember Rudolph was hitched to a single at the front of the set.

Those factors are the efficiency and power factor in the equation. Rudolph was added by Gene Autry at the last minute to light the way. He doesn't do any actual work ;-)
Sounds like Dark Energy to me; or maybe just the Higgs Field influencing my subconscious through gravity waves.
