Temperature scales like Celsius, Fahrenheit, and Kelvin are used to describe the warmth or coldness of our surroundings. Each scale has its own reference points and common uses, helping people understand temperatures in different contexts. Knowing how these scales work makes everyday information more meaningful.

Celsius is the most widely used scale for weather, cooking, and general life in many countries. Its zero and hundred degrees are based on the freezing and boiling points of water, making it easy to understand familiar temperatures like room temperature or hot summer days.

Fahrenheit is mainly used in the United States and a few Caribbean countries. Its scale is smaller per degree, which allows people to notice smaller changes in temperature. This is useful for weather forecasts, home heating, and everyday comfort.

Kelvin is mainly used in science and technology. It starts at absolute zero, where all particle motion stops, and provides a universal scale for precise measurements. While not common in daily life, Kelvin helps interpret extreme temperatures in experiments, outer space, or scientific reports.

Understanding how temperature scales work helps people make sense of weather forecasts, cook properly, stay comfortable indoors, and interpret scientific data. It also makes it easier to communicate temperatures clearly across regions that use different scales.
