Kelvin is a temperature scale primarily used in science and engineering. Unlike Celsius or Fahrenheit, Kelvin starts at absolute zero, the point where all particle movement stops. This makes it an ideal scale for precise measurements in physics, chemistry, and other technical fields.

One of the main reasons Kelvin is used in science is that it avoids negative numbers. Temperatures in Celsius or Fahrenheit can go below zero, which can be confusing in calculations. Kelvin provides a continuous scale starting at zero, making it simpler to work with in formulas and experiments.

Kelvin is also essential for understanding extreme temperatures. It is commonly used in studies of space, stars, and other environments far beyond everyday experience. Using Kelvin allows scientists to communicate temperature values universally without regional differences.

Although Kelvin is mostly used in professional and scientific contexts, understanding it helps connect real-world temperatures to absolute values. For example, everyday temperatures, boiling points, and freezing points can all be expressed in Kelvin, providing a consistent standard for comparison.

In short, Kelvin is the science-based temperature scale that provides accuracy, universality, and clarity. Learning about it helps anyone better understand how temperature is measured and applied in technical and scientific contexts.
