Absolute temperature scale

Astronomy Absolute MagnitudeAbsolute Visual Magnitude

absolute temperature scale (NASA SP-7, 1965) A temperature scale based upon the value zero as the lowest possible value. Thus, all obtainable temperatures are positive. The Kelvin and Rankine scales are absolute scales.

 


The kelvin (symbol K without the degree sign []) is also the fundamental unit of the Kelvin scale, an absolute temperature scale named for the British physicist William Thomson, Baron Kelvin.

He proposed an absolute temperature scale[11] in which a unit of heat descending from a body A at the temperature T° of this scale, to a body B at the temperature (T-1)°, would give out the same mechanical effect [work], whatever be the number T.

(Kelvin (K) is the unit for the absolute temperature scale. One Kelvin is equal to one degree Celsius. However, the absolute temperature scale is shifted by 273. So, for example, 27°C is equal to 300K. Nothing can be cooler than 0K.) ...

KELVIN - Temperature unit equal to 1° C and 1.8° F; the absolute temperature scale defined so that 0 K is absolute zero.

a unit of temperature equal to one degree on the Celsius scale and 1.8 degrees on the Fahrenheit scale; also the absolute temperature scale defined so that 0 kelvin is absolute zero
