What is Celsius(°C)?
The degree Celsius (symbol: °C) is a unit of temperature named after the Swedish astronomer Anders Celsius, who first proposed it in 1742. The Celsius scale, also known as the centigrade scale, is part of the metric system and is used worldwide for most temperature measuring purposes. The Celsius scale is defined by two points: the freezing point of water at 0 degrees Celsius (0°C) and the boiling point of water at 100 degrees Celsius (100°C) at a standard atmospheric pressure of 1 atmosphere (101.325 kPa). This means that the interval between the freezing and boiling points of water is divided into 100 equal parts, with each part being one degree Celsius.
What is Fahrenheit(°F)?
The degree Fahrenheit (symbol: °F) is a unit of temperature named after the German physicist Daniel Gabriel Fahrenheit, who proposed it in 1724. In the Fahrenheit scale, the freezing point of water is 32 degrees Fahrenheit (32°F) and the boiling point is 212 degrees Fahrenheit (212°F) at standard atmospheric pressure.
