Celsius to Fahrenheit Converter
Convert a weather, oven or body-temperature reading in Celsius into Fahrenheit before a US forecast, recipe or clinic chart.
Updated
How to use
- Enter the Celsius value, including negatives for winter weather.
- Read Fahrenheit. 0°C is 32°F; 20°C is 68°F; 100°C is 212°F.
- Oven knobs in the US are Fahrenheit. 180°C is 356°F, often labelled 350°F after rounding.
- This is not a feels-like, wind-chill or heat-index calculator.
How it works
Travellers and anyone reading a metric forecast need Fahrenheit when the next screen is a US app or a US oven. The formula is linear: multiply Celsius by 9/5 (1.8) and add 32. Water freezes at 0°C / 32°F and boils at 100°C / 212°F at standard pressure. The two scales cross at −40.
Weather is the everyday case. 10°C is a cool 50°F. 20°C is a mild 68°F. 30°C is a hot 86°F. 35°C is 95°F. Those conversions do not include humidity. A “feels like 38°C” headline is a different index.
Ovens in Europe are often Celsius. 160°C is 320°F. 180°C is 356°F (US boxes usually say 350°F). 200°C is 392°F (often 400°F on a US dial). Gas marks are a third system and are not converted here.
Core body temperature near 37°C is 98.6°F on the old textbook figure. A 38°C fever is 100.4°F. This page converts the number; it does not interpret illness.
A shortcut — double Celsius and add 30 — is only a rough indoor estimate (20°C would become 70°F instead of 68°F). Use the exact 9/5 + 32 when you are setting an oven or recording a medical number.
A change of 1°C is 1.8°F, not a second pass through +32. “It warmed 5°C” is a 9°F swing. Kelvin is Celsius plus 273.15 and is not this page.
Formula
°F = °C × 9/5 + 32
Worked examples
Freezing point of water
0 °C → 32 °F
Boiling point of water
100 °C → 212 °F
A warm room
22 °C → 71.6 °F

Useful notes
- Wind chill and heat index are not temperature conversions.
- Body temperature near 37°C is about 98.6°F.
- US oven labels often round 180°C to 350°F.
FAQ
- What is 0°C in Fahrenheit?
32°F — the freezing point of water on both common weather scales.
- What is 100°C in Fahrenheit?
212°F, the boiling point of water at standard atmospheric pressure.
- Is there a temperature that is the same in C and F?
Yes. −40°C is −40°F.
- What is 180°C in Fahrenheit for baking?
356°F. Many US recipes round that to 350°F. Check whether your recipe already did the rounding.
- What is 37°C in Fahrenheit?
98.6°F. Individual body temperature varies around that textbook value.
