What’s the difference between centigrade and Celsius? This is a common question that arises when discussing temperature measurements. Although these terms are often used interchangeably, they have distinct origins and historical contexts. Understanding the difference between them can provide insight into the evolution of temperature measurement systems. In this article, we will explore the history, usage, and similarities between centigrade and Celsius to clarify any confusion surrounding these terms.
The term “centigrade” originates from the Latin word “centum,” meaning “hundred,” and “grade,” meaning “step.” It was first introduced by Anders Celsius in 1742, who proposed a temperature scale with 100 degrees between the freezing and boiling points of water. However, the term “centigrade” was not widely adopted until later.
On the other hand, “Celsius” is named after the Swedish astronomer Anders Celsius, who developed the temperature scale. The Celsius scale is the standard temperature scale used globally, with the unit of measurement being the degree Celsius (°C). It is defined such that the freezing point of water is 0°C and the boiling point is 100°C at standard atmospheric pressure.
The primary difference between centigrade and Celsius lies in their usage and context. In scientific and technical discussions, the term “Celsius” is preferred, as it is the internationally recognized unit of temperature. However, in everyday language and historical contexts, the term “centigrade” is still used.
Another difference is that “centigrade” is an adjective, while “Celsius” is a noun. This distinction is important when discussing the temperature scale in different contexts. For instance, one might say, “The temperature is 20 degrees Celsius,” but “The centigrade scale is used in scientific research.”
Despite these differences, it is important to note that centigrade and Celsius are essentially the same temperature scale. The confusion between the two terms arises from their historical usage and the evolving standards in temperature measurement.
In conclusion, the difference between centigrade and Celsius is primarily a matter of terminology and context. While “centigrade” is an older term that refers to the temperature scale, “Celsius” is the internationally recognized unit of measurement. Understanding the history and usage of these terms can help clarify any confusion and promote accurate communication in discussions about temperature.
