How to Convert Celsius to Fahrenheit
Converting Celsius to Fahrenheit is essential when traveling between countries that use different temperature scales. This is commonly needed for weather forecasts, cooking, and scientific applications.
20.0 °C = 68.00 °F
To convert Celsius to Fahrenheit, multiply by 1.8 (or 9/5) and add 32.
Step-by-Step
- Start with your value: 20.0 °C
- Multiply by 1.8 (or 9/5)
- Add 32
- Result: 68.00 °F
Formula: °F = (°C × 9/5) + 32
💡 Memory Tip: 0°C = 32°F (freezing point of water). 100°C = 212°F (boiling point). Body temperature is about 37°C = 98.6°F.
Celsius to Fahrenheit Quick Reference
| °C | °F | Common Reference |
|---|---|---|
| -40 | -40 | Coldest (same in both!) |
| 0 | 32 | Freezing point of water |
| 20 | 68 | Room temperature |
| 37 | 98.6 | Body temperature |
| 100 | 212 | Boiling point of water |

Understanding Celsius and Fahrenheit
What is a Degree Celsius?
The degree Celsius (°C) is a unit of temperature on the Celsius scale, a temperature scale originally based on 0°C for the freezing point of water and 100°C for the boiling point of water at 1 atmosphere of pressure.

Frequently Asked Questions
20 °C equals 68.00 °F. Formula: (°C × 9/5) + 32 = °F
°F = (°C × 9/5) + 32
For 20°C: (20 × 1.8) + 32 = 68.00°F
20 °C = 293.15 K (add 273.15 for Kelvin).
20°C is warm (68.0°F). T-shirt weather.
Quick estimate: double the Celsius and add 30. For 20°C: 40 + 30 = 70°F (actual: 68°F). Close enough!
