Celsius to Fahrenheit
Convert Celsius to Fahrenheit
Frequently Asked Questions
How do I convert Celsius to Fahrenheit?
Use the formula: °F = (°C × 9/5) + 32. For example, 25°C = (25 × 1.8) + 32 = 77°F. Quick estimate: double the Celsius, subtract 10%, add 32. The converter handles both directions instantly.
What are some common temperature reference points?
Water freezes: 0°C / 32°F. Room temperature: 20-22°C / 68-72°F. Body temperature: 37°C / 98.6°F. Water boils: 100°C / 212°F. -40° is the same in both scales. These help calibrate your intuition.
Which countries use Fahrenheit?
Only the US, Bahamas, Cayman Islands, Liberia, Palau, and Micronesia use Fahrenheit as the primary temperature scale. The rest of the world uses Celsius. The converter bridges both systems for international communication.
What is the formula for Fahrenheit to Celsius?
°C = (°F - 32) × 5/9. For example, 98.6°F = (98.6 - 32) × 0.5556 = 37°C. Quick estimate: subtract 32, then halve the result (gives approximate Celsius).
At what temperature are Celsius and Fahrenheit equal?
-40° is the same in both scales. Setting °F = °C in the conversion formula: C = (C × 9/5) + 32, solving gives C = -40. This is the only point where the two scales intersect.
