Tercentesimal Temperature and the Kelvin Absolute Scale

Abstract

IN NATURE of July 19 a review entitled “Discursive Meteorology”, meaning as I think ‘discursive physics’, asks a question to which I ought if possible to find an answer. The reviewer writes: “Some of his own usages arouse criticism, in particular, that of tt to denote absolute temperature (not only in the form 300° tt, but also in formulæ); why should not meteorologists adopt the now growing physical practice of writing ‘K’ to denote the Kelvin absolute scale, just as ‘C’ and ‘F’ are used for the Centigrade and Fahrenheit scales?”
