Are you telling me they were able to measure those things, but not the boiling and freezing point of water?
Sure, let me just whip up that ammonium chloride mixture and travel somewhere where I can get it close to freezing so I can know the zero reference of that scale. What, did the just carry that NH₄Cl around for convenience?
Fahrenheit was proposed in 1724, Celsius dates back to 1742, so there wasn’t that much time between the two.
