Celsius to Fahrenheit Converter

Multiply by 9/5, then add 32. For example, 25°C: (25 × 9/5) + 32 = 45 + 32 = 77°F. Quick estimate: double it and add 30 — gives 80°F (close enough for weather).

20°C = 68°F. This is a comfortable room temperature. Other common conversions: 0°C = 32°F, 10°C = 50°F, 30°C = 86°F, 37°C = 98.6°F, 100°C = 212°F.

Nearly every country uses Celsius, including all of Europe, Asia, Africa, South America, and Oceania. Only the US, Bahamas, Cayman Islands, and a few other territories primarily use Fahrenheit.
