What is the value of absolute zero temperature?

Absolute zero is zero degrees Kelvin, equal to -273.15 degrees Celsius and -459.67 degrees Fahrenheit. The coldest known place in the universe is the Boomerang Nebula, where the temperature is -272° Celsius. read more

Absolute zero is the lower limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as 0. Absolute zero is the point at which the fundamental particles of nature have minimal vibrational motion, retaining only quantum mechanical, zero-point energy-induced particle motion. read more

Any temperature scale having absolute zero for its zero point is termed an absolute temperature scale or a thermodynamic scale. In the International System of Units, the Kelvin (K) scale is the standard for all scientific temperature measurements. read more
