Frequently asked
How many fahrenheit are in a celsius?
1 celsius equals 33.8 fahrenheit (°F).
How do I convert celsius to fahrenheit?
Use the temperature formula above — the relationship is not a simple multiplication for Celsius and Fahrenheit.
What is 10 celsius in fahrenheit?
10 °C equals 50 °F.
What is 100 celsius in fahrenheit?
100 °C equals 212 °F.
How do I convert fahrenheit back to celsius?
Reverse the formula — see our Fahrenheit to Celsius converter for the inverse calculation.
Where you'll actually use this
Temperature converters handle the only common non-linear conversions on this site — Celsius, Fahrenheit, and Kelvin all use different zero points and scale sizes.
- Cooking
Recipes from US cookbooks list oven temperatures in °F; convert to °C for European ovens (or vice versa).
- Weather
Forecasts use °C nearly everywhere except the US — 30 °C is warm (86 °F); −10 °C is freezing (14 °F).
- Science & engineering
Many physics and chemistry calculations require absolute temperature in Kelvin.
- Healthcare
Body temperature thresholds — like 38 °C (100.4 °F) for fever — need accurate conversion across regions.
Common mistakes to avoid
- Forgetting the 32-degree offset
°F = °C × 9/5 + 32. Skipping the +32 is the most common Celsius-to-Fahrenheit error.
- Treating Kelvin like Celsius
K = °C + 273.15. There is no degree symbol with Kelvin — write '300 K', not '300 °K'.
- Negative Fahrenheit ≠ negative Celsius
−40 is the one point where °F and °C are equal. Above that, the numbers diverge in opposite directions.
Did you know?
0 K (−273.15 °C / −459.67 °F) is the theoretical lowest possible temperature, where molecular motion stops.
Daniel Fahrenheit originally calibrated 100 °F to human body temperature; later measurements made it 98.6 °F.
