Convert Celsius to Fahrenheit
Celsius
Definition: The degree Celsius (symbol: °C) is a unit of temperature in the metric system, defined by setting the freezing point of water at 0°C and the boiling point at 100°C under standard atmospheric pressure.
History/Origin: Named after Swedish astronomer Anders Celsius, who introduced a similar scale in 1742. The modern definition is linked to the Kelvin scale through the relationship T(°C) = T(K) − 273.15.
Current Use: Widely used worldwide for most temperature measurements in daily life, science, and industry, except in the United States where Fahrenheit is more common.
Fahrenheit
Definition: The degree Fahrenheit (symbol: °F) is a temperature scale primarily used in the United States, defined such that the freezing point of water is 32°F and the boiling point is 212°F at standard atmospheric pressure.
History/Origin: Developed in 1724 by German physicist Daniel Gabriel Fahrenheit based on mercury thermometers and a fixed reference of brine freezing.
Current Use: Still used in the United States and a few Caribbean nations for weather forecasts, cooking, and industrial temperature measurement.
