Bawk, bawk, Rob.
Come on let's see you get all sciencey! Let's see some free-stylin'.

So do you have a problem with this? If they're equally accurate, it doesn't matter, right?No it isn't. They are simply scales to place your measurement on. Any Fahrenheit measurement can be converted to Celsius and vice versa. The limitation is accuracy of the instrument itself not whether the instrument is graduated in Celsius or Fahrenheit. Most offer both readings.
It's an easy mistake to make if your scientific knowledge base is insufficient to pass a 7th grade science quiz.
Temperatures, in the USA, are reported and recorded in whole degrees Fahrenheit. (Don’t ask why we don’t use the scientific standard. I don’t know). These whole Fahrenheit degree records are then machine converted into Celsius (centigrade) degrees to one decimal place, such as 15.6 °C.

We can't even have this conversation because you still don't understand what significant figures are.
The answer to your question is no it does not change the accuracy of the actual reading. The reading is as accurate as it is. And to know what that accuracy is you have to know where your dad is coming from and how it was read, on what instrument.
It's entirely possible that people that do not understand the importance of that such as yourself and don't understand what significant figures are they could easily think that the reading is more precise than it actually is.
I've read enough of your posts to know that you don't understand significant figures.
You've read every post I have ever written. Including all of the posts from before we ever cross paths.
Now that you read Watt and me- we are both wrong you can't explain why either of us is wrong, or even what it is we are wrong about. Got it.
Are you feeling okay? Is everything okay at home between you and the refrigerator? You seem a little down and lethargic. Normally, by now, you would have Googled for something to plagiarize and pass off as your own in order to save face.
I'm busy, Queef. Maybe I'll play later.
Did you forget you are leaning this one Luk, with Orfeo's vocabulary?
You are far too undiscipled for these games you attempt.
And you are far too insistent that there is a game being played in the first place.
Go outside and get some air.
So in the example given, Fahrenheit is converted to Celsius, and 60 Fahrenheit becomes 15.6 Celsius. Do you think it gained a significant figure in the process?We can't even have this conversation because you still don't understand what significant figures are.

There are nine degree Fahrenheit for every five degrees Celsius. It's a finer scale and therefore more accurate in whatever range of significant figures you want to use.
You didn't answer my question. Are you still looking up what significant figures are?Wrong. You can graduate Fahrenheit or Celsius by degrees or tenth of a degree hundredths of a degree as needed.
It's still a thermometer and subject to how accurate that particular thermometer is. It's a function of how far away it is from oiling or freezing not a function of what you call how far away it is.

As I said, we can't have this conversation because all you know about significant figures is what you Googled and you don't understand the concept.
the actual degree of accuracy is the actual degree of accuracy it doesn't matter if you are notating this in Fahrenheit, Celsius or pebbles that you align in rows. significant figures is going to come into play if and only if you're then collating that data and trying to decide what it means.
In you like the idiot you are look at that converted amount and see a decimal point and just decide that suddenly you have a greater degree of accuracy in the con erted centegrade row of results than of the fahrenheit row of numbers without a decimal point then you're going to get what you get when you have non mathematicians doing so-called climate science.
You do realize that if all of your initial results were in Fahrenheit and you converted them all to Celsius they would all have that particular configuration?. And you would still round or not round depending upon what is the accuracy of the least accurate bits of data that you have. A concept you still don't get.
The same thermometer can have Celsius on one side and Fahrenheit on the other, and if it can’t measure accurately or precisely, the scale used won’t improve your data. But it’ll probably find a Global Warmer that loves it!
Yes I mentioned previously that most of them actually measure in both scales.
Worldwide Celsius is much more common so most science stations are going to be in Celsius in fact even in u.s. scientific endeavors Celsius is probably used much more often. Does he really think that they're using a less accurate reading, if a very precise measuring instrument happens to be calibrated in Celsius?
Let's say you have a really long, skinny thermometer full of mercury and you've got it marked off in tenths of a degree celsius. The fahrenheit lines are closer together so you're more likely to have them in quarter and half of a degree. It's still the same exact amount of mercury that you're trying to accurately ascertain.
Measuring cups marked in cups and liters don't become more or less accurate as you eyeball it to this set of lines or that. The eyeball is the limiting factor. In a graduated cylinder the limiting factor is how skinny is that cylinder, not how the markings on it are arranged.
I wonder where he falls on the idea of using the Kelvin scale?
You are aware, I hope, that meteorologists know how to calibrate a thermometer before they take readings from it, right? And that global temperature data are collected from more than one thermometer?The same thermometer can have Celsius on one side and Fahrenheit on the other, and if it can’t measure accurately or precisely, the scale used won’t improve your data. But it’ll probably find a Global Warmer that loves it because, although both scales could be inaccurate by 20%, the precision with which it records these inaccurate readings is absolutely stunning!

I know you want to believe that thousands of scientists around the world are all fudging figures and ignoring uncertainties and resolution limits in order to get more funding for themselves. In the real world, anyone caught doing that only gets a short career.
