Temperature conversion
Celsius to Fahrenheit Converter Guide
Travelers, meteorologists, and cooks often jump between Celsius and Fahrenheit. This page shows the formula and shortcuts.
Conversion constant
°F = (°C × 9/5) + 32
Multiply Celsius by 9/5 (or 1.8) and add 32 to get Fahrenheit.
Step-by-step instructions
- 1
Choose the Temperature category inside the converter.
- 2
Enter your Celsius value in the input field.
- 3
Pick Fahrenheit as the target unit to view the converted temperature.
- 4
Use Kelvin for scientific work because the tool handles zero-offset math for you.
Conversion formula
fahrenheit = (celsius × 1.8) + 32
Fahrenheit degrees are smaller than Celsius degrees. The slopes differ by 9/5, while the intercept (32) aligns the freezing point of water.
Quick rule: double the °C value and add 30 for an approximate °F reading when speed matters.
When people use this conversion
Cooking abroad
A recipe calling for 180°C equates to 356°F, so set US ovens accordingly.
Weather planning
If a forecast lists 5°C, that is 41°F, so bundle up for morning commutes.
Quick reference table
| Celsius | Fahrenheit | Context |
|---|---|---|
| -10°C | 14°F | Winter storm |
| 0°C | 32°F | Freezing point of water |
| 20°C | 68°F | Room temperature |
| 37°C | 98.6°F | Average human body temperature |
Frequently asked questions
Why does 0°C equal 32°F?
Because Daniel Fahrenheit set 32° as the point where fresh water freezes. Anders Celsius used 0° for the same event, so the offset is baked into the formula.
What about negative numbers?
The same formula works. Multiply the negative Celsius value by 1.8 and add 32.
