Order of magnitude (temperature)
This is a compilation of temperatures of various orders of magnitude for comparison purposes. The information is often to be understood as “typical values”; the converted values are rounded.
Basic unit of the temperature in the international system of units is 1 Kelvin ( unit symbol K ), the symbols T . The degree Celsius (unit symbol ° C ) is common.
