Convert Celsius to Fahrenheit
Please provide a value below to convert Celsius [°C] to Fahrenheit [°F], or vice versa.
Celsius
Definition: Celsius is a metric temperature scale on which water freezes at 0 degrees and boils at 100 degrees, at standard atmospheric pressure.
History/origin: The scale was proposed by Anders Celsius in 1742, originally with the values reversed from today's convention.
Current use: Celsius is the standard for everyday and scientific temperature measurement in almost every country except the United States.
Fahrenheit
Definition: Fahrenheit is a temperature scale on which water freezes at 32 degrees and boils at 212 degrees, at standard atmospheric pressure.
History/origin: The scale was proposed by physicist Daniel Gabriel Fahrenheit in 1724, originally based on a brine solution's freezing point as zero.
Current use: Fahrenheit remains the everyday standard for weather and home temperature in the United States, though most of the world uses Celsius.

How to Convert Celsius to Fahrenheit
°C = (°F − 32) × 5/9
Example: convert 20°C to °F:
20°C = (20 × 9/5) + 32 = 68°F
