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?

In: Mathematics

Answer 1

Because nowadays we define the Celsius scale in terms of Kelvin and not the freezing and boiling points of water.

0 degrees C is defined to be exactly 273.15 degrees K.
