A primary standard in metrology is a standard that is sufficiently accurate such that it is not calibrated by or subordinate to other standards.Primary standards are defined via other quantities like length, mass and time.

Here, a primary standard is typically a reagent which can be weighted easily, and which is so pure that its weight is truly representative of the number of moles of substance contained.
