Morphology

kelvin + scale

The phrase is compositionally built from the unit name 'kelvin' and the noun 'scale' (a system of measurement), so a learner who knows both words can infer it refers to a temperature-measurement system using kelvins. While finer scientific details (e.g., absolute zero or relation to Celsius) require domain knowledge, the core meaning is directly derivable from the constituents.

Etymology

The Kelvin scale is named after a scientist called Lord Kelvin and measures temperature from 'absolute zero', the coldest point where all motion stops. Its units, called kelvins, are the same size as degrees Celsius, so scientists use this scale when they want a clear zero point for measurements.
