n.

The temperature at which substances possess no thermal energy, equal to -273.15°C, -459.67°F, or 0 K.

absolute zero,

the temperature at which all molecular activity except vibration ceases. It is a theoretical value derived by calculations and projections from experiments with the behavior of gases at extremely low temperatures. Absolute zero is estimated to be equal to -273° C or -460° F.
