What Is a Celsius to Fahrenheit Converter?
A Celsius to Fahrenheit converter instantly translates temperatures between the two most widely used scales. Celsius (°C) is the standard in most of the world, while Fahrenheit (°F) is primarily used in the United States for everyday weather, cooking, and body temperature.
The °C to °F formula is: °F = (°C × 9/5) + 32. The reverse —Fahrenheit to Celsius — uses: °C = (°F − 32) × 5/9. Our converter handles both directions in real time. Just type in either field and the other updates instantly.
Common reference points: 0°C = 32°F (freezing), 37°C = 98.6°F(body temperature), 100°C = 212°F (boiling). The two scales are equal at−40°.
Temperature Conversion Formulas
°F = (°C × 9/5) + 32
Example: 100°C → (100 × 1.8) + 32 = 212°F
°C = (°F − 32) × 5/9
Example: 98.6°F → (98.6 − 32) × 0.5556 = 37°C

Frequently Asked Questions
What is the formula to convert Celsius to Fahrenheit?
The formula is: °F = (°C × 9/5) + 32. For example, 100°C × 9/5 = 180, plus 32 = 212°F (boiling point of water).
What is the formula to convert Fahrenheit to Celsius?
The formula is: °C = (°F − 32) × 5/9. For example, 98.6°F − 32 = 66.6, times 5/9 = 37°C (normal body temperature).
At what temperature are Celsius and Fahrenheit equal?
Celsius and Fahrenheit are equal at −40°. Both scales intersect at −40°C = −40°F.
What is normal body temperature in Fahrenheit?
Normal human body temperature is 98.6°F (37°C). A fever is generally considered to be above 100.4°F (38°C).
What is 0°C in Fahrenheit?
0°C equals 32°F — the freezing point of water at sea level.
What is room temperature in Celsius and Fahrenheit?
Room temperature is typically 20–22°C (68–72°F). The most commonly cited value is 20°C = 68°F.
