How to convert celsius to fahrenheit
Celsius (°C) and Fahrenheit (°F) both measure temperature. Whether you are studying, traveling, cooking, or working on a project, converting between them should be fast and accurate.
Looking for the opposite direction? See our dedicated fahrenheit to celsius converter — same formula reversed, with content written for that direction.
The standard relationship used on this page means that 1 celsius equals 33.8 °F. Enter any number in the calculator — use the swap button to reverse the direction without leaving the page.
20°C is 68°F — close to room temperature on a warm day. Water freezes at 0°C (32°F) and boils at 100°C (212°F).

When you'll use this
- Reading a European or international weather forecast in °C and understanding it in the °F scale used daily in the US
- Converting a European recipe's oven temperature (°C) for a US oven that only displays °F
- Setting an air conditioner or thermostat correctly in an international rental that defaults to Celsius
- Understanding a hot tub, pool, or sauna temperature reading given in °C
- Converting a fever reading from a European digital thermometer (usually °C) into the °F scale familiar to US parents
Practical note
Weather and cooking are the two biggest reasons people land on this page. A European weather app forecasting "28°C" converts to about 82.4°F, the number that actually tells a US traveler whether to pack shorts or a jacket. In the kitchen, a European recipe calling for a "180°C oven" converts to 356°F, close enough to round to the common US "350°F" setting most home ovens use for baking — a conversion worth getting right, since setting a US oven to 180°F instead (a common mix-up) would leave a cake completely raw after the recipe's stated bake time.
Tips
- A fast mental estimate: double the Celsius figure and add 30 — it is not exact, but it gets you close enough for weather-forecast purposes.
- Body temperature is a common source of confusion: a healthy 37°C body temperature converts to 98.6°F, not the "100" some people assume when converting quickly.
- 0°C (freezing) is 32°F and 100°C (boiling, at sea level) is 212°F — these two fixed points are worth memorizing as sanity checks for any conversion.
