<P> Absolute zero is the lower limit of the thermodynamic temperature scale , a state at which the enthalpy and entropy of a cooled ideal gas reaches its 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 . The theoretical temperature is determined by extrapolating the ideal gas law ; by international agreement , absolute zero is taken as − 273.15 ° on the Celsius scale ( International System of Units ) , which equates to − 459.67 ° on the Fahrenheit scale ( United States customary units or Imperial units ) . The corresponding Kelvin and Rankine temperature scales set their zero points at absolute zero by definition . </P>
