"Degree Celsius" and "Celsius degree" refer to the same unit of temperature measurement, which is the Celsius scale. However, the order in which the terms are used can convey different meanings.
"Degree Celsius" is the more commonly used and accepted term. It represents the standard unit for measuring temperature on the Celsius scale. The symbol for degree Celsius is "°C". For example, if you say that the temperature is 25 degrees Celsius (25°C), it means that the temperature is 25 units on the Celsius scale above the zero point.
On the other hand, "Celsius degree" is less commonly used and may be considered less precise. It is a less standard way of expressing temperature and is not widely recognized or recommended by scientific organizations. While it is technically interchangeable with degree Celsius, it is more likely to be used in casual or colloquial contexts.
In summary, "degree Celsius" is the preferred and standard way to express temperature on the Celsius scale, while "Celsius degree" is less common and may be used informally. However, it's important to note that both terms refer to the same unit of temperature measurement.
