The 1880-S Morgan is very common. Average retail value of an MS-62 coin is $50.00. If by 'RPM" you mean repunched mintmark, this specific die variety is also very common for this date/mint issue Morgan. It would have little extra value.
a mass/weight unit cannot be converted into rpm, because rpm is unit of angular velocity.
It depends on the radius of the centrifuge. a=R x (angular frequency)^2 The units of angular frequency are radians/second, you want rpm If the rpm is 1 rpm the the angular frequency is 2pi *60 radians/sec

The value of a 78 rpm record typically depends on factors like rarity, condition, and demand from collectors. Sets of records, such as the "Sounds of Time," can vary in value from a few dollars to potentially hundreds of dollars, especially if they are in good condition and sought after by collectors. It's always best to research specific titles and conditions to get a more accurate estimate of value.

Priceless...
I bet alot.. I want one!
You should have about 10 PSI per 1000 RPM; a touch higher at low RPM and a tough lower at high RPM. If you car idles at around 800 RPM, 10-15 PSI is good. The 250 - 275 value mentioned by another poster would likely blow oil past all of your seals if it were possible ot get oil preasure that high.
it is unfortunately worth only a dollar or two... there is currently an unsold copy in great shape on eBay for $4.95 that remains unsold...
The symbol for RPM International Inc. in the NYSE is: RPM.
