Not illustrated. 1920 Excerpt: ... man's observations and experiments with those of other people it is most convenient to graduate all thermometers in the same way. The thermometers used in this country are divided up in two ways--(1) the Centigrade scale, (2) the Fahrenheit scale. A third scale--the Reaumur scale is extensively used in Germany. The Centigrade Scale.--Here the freezing point is called zero or no degrees Centigrade, written 6 C. The boiling point is called one hundred degrees Centigrade, and is written 100 C. The space between these two limits is divided into 100 parts, and each division called a degree Centigrade. The Fahrenheit Scale.--On thermometers marked in this way the freezing point is called thirty-two degrees Fahrenheit, written 32 F., and the boiling point two hundred and twelve degrees Fahrenheit, written 212 F. The space between the two limits is divided into 180 parts, and each division is called a degree Fahrenheit. The reason of this difference is interesting. The physicist Fahrenheit, after whom the thermometer is named, got, as he thought, a very low tem"botlingPointoFWater perature, by mixing x common salt with the M pounded ice when M measuring the lower OT fixed point, and he,0 wrongly imagined that,0 he had got the lowest temperature which could be reached, and called it zero. The Reaumur Scale.--Upon thermometers graduated according to this scale the freezing point is marked o and the boiling point 8o. The relation between the three scales is shown in Fig. 133. 0, -Melting point of ice Centigrade Fahrenheit Reaumur F1g 133.--Thermometer scales. Conversion of Scales.--It should be clear from what we have said that the interval between the boiling and freezing points, that is, the same temperature difference, is divided into 100 parts on the ...
