Celsius to Fahrenheit Converter

Conversion

Converting Celsius to Fahrenheit is one of the most common temperature conversions, especially when traveling between countries that use different temperature scales or when following international recipes and weather reports.

Conversion Formula

°F = (°C × 9/5) + 32

Example: 20°C = (20 × 9/5) + 32 = 36 + 32 = 68°F

Quick Reference Table

Celsius (°C)Fahrenheit (°F)
-40°C-40°F
-20°C-4°F
0°C32°F
10°C50°F
20°C68°F
30°C86°F
37°C98.6°F
100°C212°F

Common Uses

  • Weather Reports: Converting European weather forecasts to US format
  • Cooking & Baking: Converting oven temperatures for international recipes
  • Travel: Understanding local temperature when visiting the United States
  • Science & Medicine: Converting laboratory and medical measurements
  • HVAC Systems: Setting thermostats and climate control systems

Quick Mental Conversion Tips

  • Approximate method: Multiply by 2 and add 30 (close for everyday temperatures)
  • Exact method: Multiply by 1.8 and add 32
  • Remember: -40°C = -40°F (the only point where both scales meet)
  • Body temperature: 37°C = 98.6°F (easy reference point)

Historical Context

The Celsius scale, originally called centigrade, was developed by Swedish astronomer Anders Celsius in 1742. The Fahrenheit scale was created by German physicist Daniel Gabriel Fahrenheit in 1724. While most of the world uses Celsius, the United States, Bahamas, Belize, and the Cayman Islands primarily use Fahrenheit for everyday temperature measurements.
