Kelvin scale

The Kelvin scale is a temperature measurement system used primarily in science and engineering. Unlike Celsius or Fahrenheit, it starts at absolute zero, the point where particles have minimum energy and stop moving—a temperature of 0 Kelvin (K). The scale increments are the same size as Celsius degrees, so 1 K difference equals 1°C difference. Kelvin is useful because it provides an absolute reference point for temperature, making calculations involving energy and thermodynamics more straightforward. It’s common in scientific contexts because it directly relates to the physical behavior of atoms and molecules.
