Convert Celsius to Fahrenheit
Enter a temperature in degrees Celsius (°C) to instantly calculate the equivalent temperature in degrees Fahrenheit (°F).
Formula: °F = (°C × 9/5) + 32
How to Convert Celsius to Fahrenheit
To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5, then add 32.
Formula
°F = (°C × 9/5) + 32
Example: Convert 20°C to Fahrenheit.
20 × 9/5 = 36
36 + 32 = 68
20°C = 68°F

Common Temperature Reference Points
Celsius to Fahrenheit conversions are especially useful for weather, cooking, thermostats, travel, medical references, and scientific measurements. For quick reference, 0°C = 32°F, 20°C = 68°F, 25°C = 77°F, 37°C = 98.6°F, and 100°C = 212°F.
Celsius and Fahrenheit for Weather and Travel
Temperature conversions are particularly useful when traveling between countries that use different temperature scales. A weather forecast of 10°C is 50°F, while 20°C is 68°F and 30°C is 86°F. Knowing these common reference points can make it easier to understand outdoor conditions, choose appropriate clothing, and compare weather forecasts while traveling. For temperatures that fall between these familiar values, the Celsius to Fahrenheit converter above provides an exact conversion in seconds.
Why -40 Is Special
Celsius and Fahrenheit use different scales and starting points, but they are equal at -40 degrees. This means -40°C = -40°F, making it the one temperature where the numerical values are identical.
