Morphology

SI + system

The meaning is directly derivable because 'SI' denotes the standardized international measurement system and 'system' simply repeats that notion, so a learner who knows both constituents will understand the referent. Although slightly tautological (SI already implies a system), the phrase is compositional and clear in technical contexts, making it immediately comprehensible to B1 learners who know the parts.

Etymology

SI system gets its letters from the French words Système International, which mean 'international system' of units. It was made so everyone would use the same measurements, so SI system now means the standard metric units used around the world.
