Tool guide
What is this Converter?
The Celsius to Fahrenheit Converter is a simple online tool designed to translate temperature readings from the metric system (Celsius) to the imperial system (Fahrenheit). It also provides Kelvin as a bonus metric.
Celsius to Fahrenheit formula
Converting Celsius to Fahrenheit uses one simple formula. Multiply the Celsius temperature by 9/5 (which is 1.8), then add 32.
°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
For example, 20°C becomes (20 × 1.8) + 32 = 68°F. To reverse it, subtract 32 first and then multiply by 5/9. A quick mental estimate is to double the Celsius value and add 30, which gets you close without a calculator.
Common temperatures table
These are the temperature points people look up most often, from freezing to boiling, with body and room temperature in between.
| Celsius | Fahrenheit | What it is |
|---|---|---|
| -40°C | -40°F | Where both scales meet |
| 0°C | 32°F | Water freezes |
| 20°C | 68°F | Room temperature |
| 37°C | 98.6°F | Body temperature |
| 100°C | 212°F | Water boils |
| 180°C | 356°F | Common baking oven temp |
Why use this tool?
If you are traveling, reading an international recipe, or checking global weather forecasts, you often need a quick temperature translation. This tool gives you instant, accurate results without needing to remember complex formulas.
FAQ
Frequently asked questions
What is the formula to convert Celsius to Fahrenheit?
The formula is: (°C × 9/5) + 32 = °F.
What is room temperature in Fahrenheit?
Room temperature is typically considered to be 20°C to 22°C, which equals 68°F to 71.6°F.
Is this tool free to use?
Yes, our Celsius to Fahrenheit Converter is completely free and works directly in your browser without any signups.
What is a normal body temperature in Fahrenheit?
Average body temperature is about 37°C, which converts to 98.6°F. A reading above 38°C (100.4°F) is generally considered a fever.
How do I convert Fahrenheit back to Celsius?
Subtract 32 from the Fahrenheit value, then multiply by 5/9. For example, (98.6 - 32) × 5/9 gives you 37°C.
Does this converter handle negative temperatures?
Yes. You can enter negative values like -40°C, which conveniently equals -40°F, the one point where both scales meet.
