This should be distinguished from temperatures expressed as negative numbers on non-thermodynamic Celsius or Fahrenheit scales, which are nevertheless higher than absolute zero. A system with a truly negative temperature on the Kelvin scale is hotter than any system with a positive temperature. If a negative-temperature system and a positive ...
Most scientists measure temperature using the Celsius scale and thermodynamic temperature using the Kelvin scale, which is the Celsius scale offset so that its null point is 0 K = −273.15 °C, or absolute zero. Many engineering fields in the US, notably high-tech and US federal specifications (civil and military), also use the Kelvin and ...
The SI unit for specific heat capacity is joule per kelvin per kilogram J / kg⋅K , J⋅K −1 ⋅kg −1. Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree Celsius per kilogram: J/(kg⋅°C).
The equivalent unit compliant with the International System of Units is the kelvin-second. A quantity of kelvin-seconds is four orders of magnitude higher than the corresponding degree day (1 Celsius degree-day is 8.64×10 4 K·s; 1 Fahrenheit degree-day is 4.8×10 4 K·s).
The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.

The TI-36X Pro's Celsius to Kelvin bug In the main constants menu, there is a bug on the sixteenth menu entry for atomic mass unit, "u", which should display as "Atomic Mass U". When this entry is displayed in the top row, then scrolled down to the second row, the display incorrectly shows "Atomic Mass Ur", taking on the "r" from the next entry ...
