Celsius to Fahrenheit Converter
Convert Celsius to Fahrenheit for weather, cooking, and travel. The formula multiplies by 9/5 and adds 32, mapping 0 °C (water freezing) to 32 °F and 100 °C (water boiling at sea level) to 212 °F.
Formula
°F = °C × 9/5 + 32
Example: 25 °C × 9/5 = 45; 45 + 32 = 77 °F.

Frequently asked questions
- What is 0 °C in Fahrenheit?
- 0 °C equals 32 °F — the freezing point of water at standard pressure.
- How do I convert Celsius to Fahrenheit in my head?
- Double the Celsius value and add 30. For 20 °C: 40 + 30 = 70 °F (exact is 68). Good for weather-scale temperatures.
- At what temperature do °C and °F meet?
- At −40°. This is the single point where the two scales cross: −40 °C = −40 °F.
