There are some standard units we all understand intuitively such as:

Mass (kg) Length (metres) Time (seconds)

From these there are some familiar composite units which are also well understood:

Velocity (m/s) Force (Newtons = kg m/s^2) Energy (Joules = kg m^2/s^2)

Then there are some obscure ones such as:

Moment (kg-metres)

And then truly esoteric units that may arise usually in research:

Ex: (m/s)^(1/2) Or kg m^3/s^5 etc...

My question: ———

Is there a library of all known physical units that have appeared in some research paper or experiment/have some meaning attached to them.

Say someone runs into some obscure unit in their research. Can they go this library to find connections with other unusual areas of physics?

I can see this as being useful for making thought experiments in esoteric parts of physics.

There are plenty of lists of units, but no one is maintaining an exhaustive list of every unit that has ever appeared in a published paper. Physicists find more interesting ways to spend their time.
