Is it possible that thermometer calibration has just drifted slightly over the last couple hundred years? If you told me that the typical electronic thermometer today actually measured around a degree different than the mercury thermometer Wunderlich presumably used, I wouldn't be all too surprised.
Or is there really an accurate and consistent calibration technique that's been in use since at least the 1800s, so we know for sure that it must be humans themselves getting cooler?
- sublinear 4y agoUh surely "mmHg" is a stable unit of measurement where the calibration is self-evident by its own definition.
- hamandcheese 4y agommHg is a unit of pressure, not temperature. Mercury thermometers do need to be calibrated.
- kbelder 4y agofreezing point of water/boiling point of water are pretty stable temperature checkpoints, once we learned to fix pressure and contamination....
