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?

Absolute zero

0 K (−273.15 °C / −459.67 °F) is the theoretical lowest possible temperature, where molecular motion stops.

Fahrenheit's 100 was body temperature

Daniel Fahrenheit originally calibrated 100 °F to human body temperature; later measurements made it 98.6 °F.
