New Unit - RPM #183

Closed keilw closed 3 years ago

keilw commented 3 years ago

As for some unknown reason (maybe the original author would have to do that?) https://github.com/unitsofmeasurement/si-units/issues/75 could not be transferred here, creating this new ticket instead. Most likely this is for USCustomary since REVOLUTION is already a known unit there.

It is also called a US or English unit in https://www.mfcp.com/technical-info/basic-units or https://physik.cosmos-indirekt.de/Physik-Schule/Rpm_(Einheit)#:~:text=revolutions%20per%20minute%3B%20%E2%80%9EUmdrehungen%20pro,Zeitraum%20von%2060%20Sekunden%20an.&text=1%20rpm%20%3D%201%20min%20%3D%201%2060%20s%20.

I suppose the definition based on REVOLUTION would be

public static final Unit<Frequency> REVOLUTION_PER_MINUTE = addUnit(REVOLUTION.divide(MINUTE)).asType(Frequency.class);

Actually it seems AngularSpeed, not Frequency is the correct quantity here.
