Kel

Kel, short for Kelvin, is a temperature scale used mainly in science. It starts at absolute zero, which is the coldest possible temperature where particles stop moving, equivalent to -273.15°C. Unlike Celsius or Fahrenheit, Kelvin has no negative numbers. The scale is used to measure temperature precisely in scientific experiments, especially in physics and chemistry, because it directly relates to the energy of particles. One Kelvin unit is the same size as one Celsius degree. Kelvin helps scientists understand thermal energy without the complications of negative values, providing a clear, absolute measure of temperature.
