Morphology
The noun phrase is transparently compositional: 'compression' (applying pressure/decreasing volume) combined with 'ratio' (a numeric relation) directly yields a numeric measure describing the degree or amount of compression. Although the precise technical formulation (specific pressures in an engine or compressor) is domain-specific, the core meaning is clearly derivable from the parts and matches analogous constructions in other languages.
Etymology
The term compression ratio comes from the simple idea of compression (the 'squeezing' of a gas) and ratio (a 'comparison'). It measures how much the gas is squashed by comparing the pressure at the end with the pressure at the start, so a higher compression ratio means the gas is squeezed more and the engine can make more power or use fuel more efficiently.
