How Is Temperature Defined on Safehold?

Wrong. Celcius set 0 as the boiling point of water and 100 as the freezing point of water. The first use of the current scale came a year later, in France. Often called the "centigrade" scale, it was renamed to "Celcius" in honour of the aforementioned Anders Celcius. Personally, I don't think he deserved the honour - I would have preferred the Christin scale, after the frenchman who first developed it.

Are you certain of that?

In 1742, Swedish astronomer Anders Celsius (1701–1744) created a temperature scale which was the reverse of the scale now known by the name "Celsius": 0 represented the boiling point of water, while 100 represented the freezing point of water. In his paper Observations of two persistent degrees on a thermometer, he recounted his experiments showing that the melting point of ice is essentially unaffected by pressure. He also determined with remarkable precision how the boiling point of water varied as a function of atmospheric pressure. He proposed that the zero point of his temperature scale, being the boiling point, would be calibrated at the mean barometric pressure at mean sea level. This pressure is known as one standard atmosphere. The BIPM's 10th General Conference on Weights and Measures (CGPM) later defined one standard atmosphere to equal precisely 1013250dynes per square centimetre (101.325 kPa).[5]

In 1743, the Lyonnais physicist Jean-Pierre Christin, permanent secretary of the Académie des sciences, belles-lettres et arts de LyonFR, working independently of Celsius, developed a scale where zero represented the freezing point of water and 100 represented the boiling point of water.[6][7] On 19 May 1743 he published the design of a mercury thermometer, the "Thermometer of Lyon" built by the craftsman Pierre Casati that used this scale

If you don't believe me, just listen to people commenting about the weather. hardly anyone apart from forecasters and news reporters ever says '78 F today' or 'only 2 C so wear a coat'. Of course, some of us can and do automatically make the conversion to our favoured scale in our heads so don't care which one is used in a report.

On the other hand the Writ has injunctions against cheating people so there must be some idea of "an inch is about this much". Presumably the same goes for standards of weight and volume, but the subject in general has just never arisen in the books, except for the many discussions of linear measure.

As discussed elsewhere the archangels probably wanted a degree of variance in standards of measurement to hinder industrialisation.

Safehold did all math in Roman Numerals. Roman Numerals do not have a zero, or the concept of negative numbers. Using either of these temperature scales would create issues with numbers that cannot be written.

A simple answer is to set 1 as 'the temperature of Shan-Wei's Hell', and make it so cold as to be unattainable by man, say -200 F. All temperature are now positive numbers.
