What’s the difference between Celsius and Centigrade? This question often arises among those who are new to the metric system or are learning about different temperature scales. Although these two terms are often used interchangeably, there are subtle differences between them. In this article, we will explore the origins, definitions, and uses of both Celsius and Centigrade, and clarify the distinctions between them.
The Celsius and Centigrade scales are essentially the same temperature scale, with the only difference being the name. The Celsius scale is the more commonly used name in scientific and everyday contexts, while Centigrade is an older term that is less frequently used today. The term “Centigrade” comes from the Latin word “centum,” meaning “hundred,” and “gradus,” meaning “step.” This name was chosen because the scale was based on dividing the difference between the freezing and boiling points of water into 100 degrees.
The Celsius scale was developed by Swedish astronomer Anders Celsius in 1742. Initially, Celsius proposed a scale where the freezing point of water was 0 degrees and the boiling point was 100 degrees. However, his original scale was reversed, with the boiling point at 0 degrees and the freezing point at 100 degrees. It was later corrected by Carl Linnaeus, a Swedish botanist, and the scale was renamed in Celsius’s honor.
On the other hand, the term “Centigrade” was introduced by Carl Linnaeus, who also played a significant role in the development of the Celsius scale. The term “Centigrade” was used to describe the scale based on the 100-degree division of the water’s temperature range. Over time, the name “Celsius” became more popular and is now the standard term used worldwide.
So, what’s the difference between Celsius and Centigrade? In essence, there is no difference in the actual temperature scale. The only difference lies in the names. Celsius is the preferred term in most countries, while Centigrade is a term that is no longer widely used. It is important to note that the Celsius scale is also known as the centigrade scale, but the term “Centigrade” is not commonly used in scientific or everyday language.
In conclusion, the Celsius and Centigrade scales are the same temperature scale, with the only difference being the name. The Celsius scale is the more widely recognized and used term, while Centigrade is an older, less common name. Understanding the origins and definitions of both terms can help clarify any confusion and ensure accurate communication when discussing temperature.
