A number that shows how well sunscreen protects your skin from the sun's harmful rays

is the shortened written form used instead of the full phrase

Surface Forms

SPF singular
SPFs plural

Morphology

SPF = sun + protection + factor (semi-transparent) = S + P + F

The abbreviation is a direct initialism of 'sun protection factor', so the relation to the descriptive phrase is clear. [Postprocessing: changed transparency from 'transparent' to 'semi-transparent' for abbreviation]

Etymology

SPF stands for Sun Protection Factor, which literally means 'how much a product protects your skin from the sun'. So a higher SPF number means more protection from sunburn.
