At least I have several 3/12" inch wrenches when I need them. 
Fractions are ridiculous - 3/8, 9/32, 9/16, 15/64. With mm, it's obvious which is larger and which is smaller - 5mm is more that 2mm.

I just convert a measure if I need to compare them - for example 3/8 = 12/32 = 24/64

OK... if I remember correctly I did say b about /... (show quote)
Nope, it isn’t “about 274”, it’s “about” 273 (precisely 273.15), and every student that’s taken Chem 101 knows that, just like Avogadro’s number... if your’re going to discuss chemistry and physics where there are absolutes, precision and correct facts are important.

Nerd bomb alert! Because the 'size' of Farenheit degrees is smaller than that of a Celcius degree, it takes more to cover a given temperature span. Two ramifications. Generally, at temperatures found on Earth, Farenheit will be a higher value, but at quite low temperatures, Farenheit ends up as a lower reading. Also -40 degrees is the same reading Farenheit or Celcius. By that info, I'm guessing your last two formulas only work for positive values on each scale.
Ha ha - it seems that you're correct. Interesting that -40c = -40f.

So far this thread has been one of the most entertaining in a while, and I see that everybody is online which means you do agree. Except maybe about C and F.

That's kewl, but C x 1.8 + 32. for conversion to Fahrenheit works for all temps and is about as simple as it gets.
It's certainly the shortest formula - but my brain works better on x2 -10%. Actually 2-10% =1.8

To put this discussion in perspective as far as something to worry about, just wait until the robots take over and we have to switch to the binary number system instead of our 10-based system. Try converting from C to F in binary and please don't cite an example to show you can.

Is that when you put 2 and 2 together??? . . .

It won't matter.
Everything will be in whatever form is convenient for their human users.

if it makes you happy to be argumentative over a fraction of a single degree, knock yourself out.

For the bibliophiles amongst us, here is a good book about the metric system that I read years ago.

And this is a good follow-up story:

You have countries that use the metric system and then you have countries that have been to the moon.
But they went to the moon using the metric system.

I met a cockatoo with more interesting things to say than the stuff you parrot.

That could be true but does he know the difference between C and F? . . .
