degree Fahrenheit [F] to degree Celsius [C] Converter

Quick Reference

1 degree Fahrenheit (F) = -17.22222222 degree Celsius (C)

1 degree Celsius (C) = 33.8 degree Fahrenheit (F)

How to Convert degree Fahrenheit to degree Celsius

1 F = -17.22222222222222 C
1 C = 33.8 F

To convert degree Fahrenheit to degree Celsius, divide the value by 33.8 (equivalently, multiply by -17.22222222). To convert degree Celsius back to degree Fahrenheit, multiply by 33.8.

Example: convert 10 F to C:
10 F = 10 x -17.22222222222222 = -172.22222222222223 C

↔ Convert degree Celsius to degree Fahrenheit

degree Fahrenheit

Definition: Degree Fahrenheit (°F) is a unit of temperature on the Fahrenheit scale, where the freezing point of water is 32 °F and the boiling point is 212 °F at standard atmospheric pressure.

History/origin: The Fahrenheit scale was developed in 1724 by the German physicist Daniel Gabriel Fahrenheit. He based his scale on the freezing point of a brine solution (0 °F) and the approximate body temperature of a human (96 °F, later adjusted to 98.6 °F).

Current use: Degree Fahrenheit is primarily used in the United States, its associated territories, and a few other countries for weather reporting and everyday temperature measurements.

degree Celsius

Definition: Degree Celsius (°C) is a unit of temperature on the Celsius scale, which is defined so that the freezing point of water is 0 °C and the boiling point is 100 °C at standard atmospheric pressure.

History/origin: The Celsius scale was originally proposed in 1742 by the Swedish astronomer Anders Celsius. He originally defined 0 °C as the boiling point of water and 100 °C as the freezing point, but this was later reversed to its current definition.

Current use: Degree Celsius is the standard unit of temperature used in most of the world, except for the United States and a few other countries. It is used in scientific research, weather reporting, and everyday life.
