SI unit
Noun
pl: SI units
This term refers to the globally recognized standard for scientific measurement. It is used primarily in academic, technical, and scientific registers to ensure consistency across international borders, contrasting with regional systems like the Imperial or US Customary systems.
Because it is a compound noun consisting of an acronym and a common noun, the pluralization occurs on the word "unit." It is used as a countable noun when referring to specific individual units (e.g., the meter, the second) or as a general category of measurement.
