Attention: Do not re-enter the exact number of a calculated answer.
At 0 K according to -273,15�C the thermal energy and thus the oscillatory motion of the electrons and particles
come to stop. Therefore there is no lower temperature than -273,15�C, even if that can be entered here.
The degree centigrade (�C) was officially renamed Celsius in 1948 to avoid confusion
with the angular measure known as the centigrade (one hundredth of a grade).
