Celsius and Fahrenheit
Aug 8, 2020 11:04:03 #
Celsius is used by most of the world and also by scientists. When we hear that sea temperatures have increased by 2° C, some people laugh and think that's nothing. In terms of Fahrenheit, that's 3.6°, and it is significant, especially since the poles are heating up more quickly than the rest of the planet - and ice is melting.
What made me post this was a news article about the excessive heat and lack of water out west.
"...the border in eastern Utah — has warmed more than 2 degrees Celsius, double the global average."

In C of F, it's still the same relative temperature differential.
Representing in F does not make it worse.
What is it in Kelvin?

It's about time that America adopts the metric system to come in line with the rest of the world. . .

But a translation from C to F makes the temperatures more meaningful to us.
I remember flying down to Venezuela many years ago in our Winter;
when the pilot announced the outside temperature as being something like 40 C, I thought nothing of it until I converted it to F!

...as a carpenter, which means I'm an ingrained inch guy, I agree. My brother, the machinist, has been metric forever...

True, it does not make it worse. The difference lies in the perception of people that are not familiar with a system they are not use to.

As a woodworker it is perfectly natural for you to use the word "ingrained" in your comment . . .

While true, for the relative meaning to people, it will also make people think that the difference is HOTTER, which it is NOT. Only the numbers repersenting the thermal value are different, not the actual amount of heat. Bigger difference has to be hotter, right?
That's what I was trying to point out. A change of 2° C and a change of 3.6° Fahrenheit is the SAME AMOUNT of heat differential. One is not a higher (hotter) or lower (cooler) amount of heat.

There was a big push for that a few decades ago, and it fizzled. I worked In the Aerospace industry for awhile, and we built parts to both systems, but probably 80% of our orders (which came from all over the world) were for American threads and inches and the remainder metric, and all our machine tools were calibrated and programmed in inches and oz/lbs - probably because a large percentage of aerospace and defense contractors are American. I think it’s so ingrained into our fasteners, tools and culture that it’s unlikely to change anytime soon.

Haha...I was wondering. ;0)

I agree that it will not be anytime soon, and may in fact never happen. The cost of conversion would be enormous simply because both systems would have to be maintained for a very long time for obvious reasons.

And unfortunately, guess what they will think...

Exactly!!! and I have witnessed head-shaking arguments taking place over this issue.
