The celcius was designed without regard to the temperature of absolute zero. Why does the exact value of absolute zero only have 2 decimal points in the celcius scale?

Question

Isn’t it quite a big coincidence that this value would only have 2 decimal points on a scale that puts the temperature value of water boiling and freezing at whole numbers?

Answer 1

Cuz in reality it likely isn’t, but for practical uses going to more decimal places isn’t that helpful. The same way that we round pi to 3.14 instead of using 3.14159…

Like in many engineering applications we don’t even use 273.15, we just round it to 273. Absolute Zero is just a hypothetical point where you cool a gas down to the point where its Volume is 0. But gas is matter, physical atoms, it is impossible to make those atoms have no volume.
