HOT again. Only about 35° C today, unlike the 41° C we had yesterday; but still mighty uncomfortable. And even indoors my phone is overheating. Ugh.
These conditions were tolerable in Nebraska or Texas, since most places have air conditioning. But with the temps rarely exceeding 26° C here, almost no places have it.
Kelvin and Celsius are basically the same yardstick, just shifted by a constant (273.15). Fahrenheit is different because it requires a multiply or divide and a constant.
All this doesn’t matter, the important is that you understand what the other is saying.
It’s a scale, and you have learned what representation has your feeling of “cold”. 10 Degrees Celcius? 50 degrees Fahrenheit? It’s only the name. The important is that we understand what we are talking about.
How do you figure that when Farenheit came before Celsius? According to their wikipedia pages, Farenheit came in 1724, and Celsius (Centigrade) in 1743. And Kelvin in 1848.
Edit: Oh, but you say it’s that way “these days” … Not sure what you’re trying to say there.
