Which scale do you prefer and why? I’m largely in favor of Fahrenheit and or Rankine. As anyone who has ever fought over a thermostat knows you can feel the difference between 71 and 73 F. That’s 21.6 and 22.7 C. Just isn’t as neat, takes up more room on displays, and takes longer to say verbally. The Fahrenheit scale seems based around human perception while Celsius is all about water. Considering we have Kelvin and Rankine for scientific needs I don’t really see a use for Celsius. In that same vein if we were ever to unify scientific and creature comfort scales I’d vote for Rankine as it uses the Fahrenheit stepping.
