Celsius to Fahrenheit
Avoid freezing without a coat or burning your dinner. Translate generic "degrees" into a temperature you actually understand.
Formula: (°C × 9/5) + 32 = °F
A Tale of Two Scales
The world is divided. Most of the planet uses the Celsius scale, based on the logical freezing (0°) and boiling (100°) points of water. The United States, however, clings to Fahrenheit, a scale based on... brine and human body temperature? Traveling between these zones can be confusing. "It's 25 degrees" means a pleasant summer day in Paris (Celsius) but a deep freeze in New York (Fahrenheit). Our Temperature Converter eliminates the confusion instantly.
Quick Reference Guide
Memorize these benchmarks to survive travel or cooking:
Water Freezes
0°C = 32°F
Below this line, you need a winter coat and roads get icy.
Room Temp
20°C - 22°C = 68°F - 72°F
The standard setting for office thermostats and comfortable living.
Human Body
37°C = 98.6°F
If you are significantly above this, you have a fever.
The Mental Shortcut
Don't have a calculator? Use this rough approximation to convert Celsius to Fahrenheit in your head:
Example for 20°C:
Actual Math: (20 * 1.8) + 32 = 68°F
Mental Math: (20 * 2) + 30 = 70°F
Close enough to know what to wear!
Cooking & Baking
Your British recipe says "Bake at 180°C." In your American oven, that equates to 350°F—the standard baking temperature.
Fever Checks
Digital thermometers often switch modes accidentally. Knowing that 39°C is a high fever (102.2°F) is critical medical knowledge.
Science & PC Hardware
CPU temperatures are always measured in Celsius. If your gaming PC hits 90°C, it's dangerously hot (194°F).
Frequently Asked Questions
What about Kelvin?
Kelvin is the scientific scale. It has no negative numbers because 0 K is "Absolute Zero"—the point where all molecular motion stops. 0 K = -273.15°C.
How do I convert Fahrenheit to Celsius?
Subtract 32, then multiply by 5, then divide by 9. Example: (68 - 32) * 5 / 9 = 20°C.
Why is the factor 1.8?
Between freezing (32°F / 0°C) and boiling (212°F / 100°C), there are 180 Fahrenheit degrees and 100 Celsius degrees. 180 divided by 100 equals 1.8 (or the fraction 9/5).
Approximations
While the math is exact, environmental factors like altitude can affect the boiling point of water, making the physical benchmarks slightly variable.
