How to Convert Celsius to Fahrenheit
To convert Celsius to Fahrenheit, multiply by 9/5 (1.8) and then add 32. For example, to convert 10 °C to °F, calculate using the exact formula: °F = (°C * 9/5) + 32. The reverse transformation is calculated as °C = (°F - 32) * 5/9.

| Celsius (°C) | Fahrenheit (°F) |
|---|---|
| -40 °C | -40 °F |
| -10 °C | 14 °F |
| 0 °C | 32 °F |
| 10 °C | 50 °F |
| 20 °C | 68 °F |
| 25 °C | 77 °F |
| 30 °C | 86 °F |
| 37 °C | 98.6 °F |
| 40 °C | 104 °F |
| 100 °C | 212 °F |
| 180 °C | 356 °F |
| 200 °C | 392 °F |
Step-by-Step Worked Calculation Examples
Here are 3 real-world scenarios demonstrating how this conversion is applied in practice:
Example 1: Normal Human Body Temperature (37 °C)
37 °C body temperature equals (37 * 1.8) + 32 = 98.6 °F.
Example 2: Water Boiling Point (100 °C)
100 °C at sea level equals (100 * 1.8) + 32 = 212 °F.
Example 3: Water Freezing Point (0 °C)
0 °C water freezing equals (0 * 1.8) + 32 = 32 °F.
Example 4: Extreme Parity Point (-40 °C)
-40 °C equals (-40 * 1.8) + 32 = -40 °F (the unique point where both scales coincide!).
Common Conversion Pitfalls & Mistakes
- Forgetting to add 32 after multiplying by 1.8.
- Adding 32 first before multiplying (order of operations error).
- Using 2 instead of 1.8 for quick estimation without realizing it creates large deviations at oven temperatures.
