What is a quarter (UK) in mass terms?

A quarter (UK) is a traditional British mass unit equal to one quarter of a long hundredweight, which is 28 avoirdupois pounds or about 12.70058636 kilograms.

Why convert quarter (UK) to proton mass?

This conversion helps relate historical macroscopic mass units to microscopic masses used in nuclear and particle physics and chemistry.

Are the conversion results precise?

Conversion relies on the recommended CODATA value for proton mass, but slight variations may exist with future updates to constants.
