Converting Celsius to Fahrenheit
Converting from Celsius to Fahrenheit is one of the most common temperature conversions, especially for travelers moving between countries that use different temperature scales.
Mathematical Relationship
The formula to convert Celsius to Fahrenheit is: °F = (°C × 9/5) + 32. Unlike simple unit conversions, this involves both multiplication and addition due to the different zero points of the scales.
Common Conversion Values
| Celsius | Fahrenheit |

Unit Definitions
Celsius
The Celsius scale (symbol: °C) is a temperature scale used by the International System of Units (SI). It defines 0°C as the freezing point of water and 100°C as the boiling point of water at standard atmospheric pressure.
Fahrenheit
The Fahrenheit scale (symbol: °F) is a temperature scale based on one proposed by physicist Daniel Gabriel Fahrenheit in 1724. In this scale, the freezing point of water is 32°F and the boiling point is 212°F at standard atmospheric pressure.
Historical Context
The Celsius scale was proposed by Swedish astronomer Anders Celsius in 1742, though it was initially reversed (0° was boiling, 100° was freezing) before being standardized in its current form. The Fahrenheit scale was proposed earlier in 1724 by Daniel Gabriel Fahrenheit, a Polish-German physicist.
Additional Information
The Celsius scale is used in most countries around the world, while the Fahrenheit scale is primarily used in the United States and its territories.
