Absolute zero (0 Kelvin) equals exactly
-273,15 degrees Celsius
Absolute zero is the theoretically lowest possible temperature in the universe, the point at which the particles of a system would have the minimum possible kinetic energy. It corresponds to 0 Kelvin, or -273.15 degrees Celsius. According to the laws of thermodynamics, this temperature cannot be exactly reached, only approached asymptotically.
To convert from Kelvin to Celsius (useful for understanding where absolute zero sits), subtract 273.15:
In Fahrenheit, absolute zero corresponds to:
The concept of absolute zero is one of the most fascinating notions in physics, and is often searched for general knowledge and scientific curiosity. It's important to know that, although scientists have managed to cool matter to fractions of a degree above absolute zero in laboratories, reaching it exactly would violate the third law of thermodynamics, and is therefore considered physically impossible.
