the only temperature scale that starts at the absolute end of motion.
means A unit and scale of absolute temperature in which zero marks the complete absence of thermal motion, with each kelvin equal in size to one degree Celsius.
from Named for the Scots-Irish physicist William Thomson, who became Lord Kelvin — a title he took from the River Kelvin that flows past Glasgow University, where he worked. So the unit honoring the coldest conceivable temperature is named, fittingly enough, after a chilly Scottish river. The scale was proposed in the mid-19th century; the modern name 'kelvin' was formally adopted in 1968, lowercase as a unit, capital K as its symbol.
- degree drop
- Officially just kelvins, never degrees Kelvin
- zero point
- 0 K is minus 273.15 Celsius, all motion stilled
- named for
- Lord Kelvin, born plain William Thomson
- redefined
- Since 2019, defined by the Boltzmann constant
- unreachable
- Absolute zero can be approached but never touched
