The degree Celsius, named after the Swedish astronomer Anders Celsius, is a unit of temperature with a fascinating dual nature. While it’s widely used every day for weather forecasts and cooking, it’s also pivotal in scientific endeavors. Celsius is part of the metric system, which makes it compatible with the Kelvin scale used in scientific research. Interestingly, Celsius was initially devised with an inverted scale, where 100 represented the freezing point of water and 0 its boiling point. It was only after Celsius’s death that Carolus Linnaeus, another Swedish scientist, reversed it to the standard we use today.

This unit is essential for understanding the physical properties of materials. For instance, the Celsius scale aligns perfectly with the properties of water, a substance vital for life on Earth. The fact that water freezes at 0°C and boils at 100°C under standard atmospheric conditions makes it convenient for daily temperature assessments. This simplicity helps avoid the complications of Fahrenheit, which is commonly used in the United States but does not share the intuitive reference points of Celsius.
