What is the absolute zero temperature

Absolute zero is a temperature point at -273.15°C in the familiar Celsius scale, where 0° C is the freezing point of water and the boiling point is 100° C.

On the Fahrenheit scale this is -459.67° F.
On the Fahrenheit scale, water freezes at 32° F, and water boils at 212° F, separating the two states by 180°. Another temperature scale, called the Kelvin scale, uses the same size units as the Celsius scale, but defines 0° K (zero kelvins) as absolute zero.

Absolute zero is the lowest temperature theoretically attainable, a limit point where all molecular particles are at their absolute minimum energy potentials.
the Kelvin and Celsius scales are used in science.

−459.67 degrees on the Fahrenheit scale or −273.15 on the Celsius scale.
