Question

if the absolute temperature of gas is 600k, the temperature in degree celsius is?

Answer 1

it is 326.85 degrees Celsius

Answer 2

The unit conversion form degree celsius to Kelvin is

273.15 +C = K

if given 600K, then
C= 600 -273.15


on a side note, 0K is absolute zero, the coldest theoretical temperature possible, which correlates to -273.15 C
