Fahrenheit to Celsius Converter

Use our Fahrenheit to Celsius converter to quickly and accurately convert temperatures from degrees Fahrenheit (°F) to degrees Celsius (°C). Enter a temperature in the calculator below to get the equivalent Celsius value instantly.

How to Convert Fahrenheit to Celsius

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature, then multiply the result by 5/9.

Fahrenheit to Celsius Formula

°C = (°F − 32) × 5/9

Example: Convert 68°F to Celsius.
68 − 32 = 36
36 × 5/9 = 20
68°F = 20°C

Common Uses of Fahrenheit and Celsius

Fahrenheit and Celsius are used in many everyday situations, but their use varies by location and purpose. Fahrenheit is commonly used for weather forecasts, household temperatures, and cooking in the United States, while Celsius is widely used for these purposes in most other countries. Celsius is also commonly used in scientific, educational, and technical settings. Understanding both temperature scales can be especially helpful when traveling internationally, following recipes from another country, comparing weather information, or working with products and instructions that use a different temperature scale.

About Fahrenheit

Fahrenheit, represented by the symbol °F, is a temperature scale commonly used in the United States. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F at standard atmospheric pressure.

About Celsius

Celsius, represented by the symbol °C, is a temperature scale used throughout most of the world and widely used in science and the metric system. On the Celsius scale, water freezes at 0°C and boils at 100°C at standard atmospheric pressure.

For additional information about temperature units and exact Fahrenheit-to-Celsius conversions, visit the U.S. National Institute of Standards and Technology (NIST).

Understanding the difference between these temperature scales is especially useful when comparing weather forecasts, cooking temperatures, travel information, scientific measurements, and other temperature references from different countries. Fahrenheit is commonly used in the United States, while Celsius is widely used throughout most of the world. An accurate Fahrenheit to Celsius conversion helps ensure that temperatures are interpreted and compared correctly.
