So, I was left with the impression that Fahrenheit is simply better for Heating plus A/C systems than Celsius
Quite simply, when you turn the control component on an air conditioning component up or down 1° C, you are jumping farther up or farther down than you would be on the Fahrenheit scale. 20° C is about 69° F. Initially, I was extremely comfortable with this temperature on our first evening in the hotel, but throughout the course of the evening, it felt too cold, plus my wife was cold. I decided to turn it up to 21° C. I did the conversion real quick in a web browser plus found that it was now 69.8° F! Still, my wife complained that it was too cold, and once again, I turned up the temperature 1° C plus looked plus saw that was the equivalent of 82.6° F… So ultimately, a 2° difference in Celsius meant a 3.6° difference in Fahrenheit. So, I was left with the impression that Fahrenheit is simply better for Heating plus A/C systems than Celsius. Fahrenheit ultimately gives you more control over the temperature in a room.
