The PHYSICAL embodiment of a unit of measurement is a standard. For example, the fundamental unit of mass in the international system is the kilogram and DEFINED as the mass of a CUBIC decimeter of water at its temperature of MAXIMUM density of 4°c.

It is defined as R = ± 0.6745s where s is STANDARD deviation.
Probable ERROR has been used in EXPERIMENTAL work to some extent in PAST, but standard deviation is more convenient in statistical work.
