The formula
Fahrenheit is found by scaling and shifting Celsius:
°F = °C × 9/5 + 32
Reversed, °C = (°F − 32) × 5/9.

Frequently asked questions
- How do I convert Celsius to Fahrenheit?
- Multiply the Celsius value by 9/5, then add 32. For example, 20°C × 9/5 + 32 = 68°F. The converter above computes this live as you type.
- What is the Celsius to Fahrenheit formula?
- °F = °C × 9/5 + 32. The 9/5 scales the degree size (Fahrenheit degrees are smaller), and the +32 shifts the zero point, since 0°C is 32°F.
- What is normal body temperature in Fahrenheit?
- 37°C, the commonly cited average body temperature, converts to 98.6°F (37 × 9/5 + 32).
- What is 100°C — boiling point of water — in Fahrenheit?
- 100°C is 212°F (100 × 9/5 + 32). That’s a 180°F range between freezing (32°F) and boiling (212°F), matching the 100°C range on the Celsius scale.
- Is there a temperature where Celsius and Fahrenheit read the same?
- Yes — at -40 degrees, both scales agree: -40°C equals -40°F.
- Does this tool store or send the temperatures I enter?
- No. The conversion runs entirely in your browser with JavaScript — nothing is uploaded or logged.
