In most of the (physical) sciences,
another scale of temperature measure which is often used
is degrees Kelvin (°K). The Kelvin scale
was devised such that 0 °K
corresponds to
Absolute Zero (the temperature at which everything would
be frozen solid), where °K = °C + 273.15.
Thus,
Absolute Zero occurs at about -273.15 °C.
What Fahrenheit temperature is equivalent to
Absolute Zero (0 °K)?
