About Kelvin (K)

The kelvin is the SI base unit of thermodynamic temperature, with 0 K representing absolute zero -- the theoretical point where all molecular motion ceases. Scientists and engineers use kelvin in thermodynamics, astrophysics (the Sun's surface is about 5,778 K), and color temperature for lighting (e.g., 6500 K daylight).

About Rankine (°R)

The Rankine scale uses the same degree increment as Fahrenheit but starts at absolute zero (0 degrees Ra = -459.67 degrees F). Developed by Scottish engineer William Rankine in 1859, it is used in thermodynamic calculations within the US engineering community, particularly for gas turbine and steam power cycle analysis.
