Because Celsius is a proper noun, it functions as an invariable adjective in Spanish and does not change its ending to match the gender or number of the noun it describes.
While Celsius is the standard, many Spanish speakers still use centígrados in daily life, as it often sounds more natural and less academic than the official term.
