Enter a temperature in Celsius and press Convert to get Fahrenheit. 180 °C is 356 °F, the standard baking temperature.
About the Celsius to Fahrenheit Converter
Celsius and Fahrenheit do not share a zero, so this is not a simple multiply. A Fahrenheit degree is 5/9 of a Celsius degree — there are 180 Fahrenheit degrees between freezing and boiling against 100 Celsius degrees — and the scales are offset by 32 °F at the freezing point of water.
The two scales cross at −40 °: −40 °C is exactly −40 °F. That is a handy sanity check, and it is also the only value where a conversion error is invisible.
How the calculation works
- °F = (°C × 9/5) + 32
- °C = (°F − 32) × 5/9
- A change of 1 °C equals a change of 1.8 °F
Reference values
| Celsius | Fahrenheit | Reference |
|---|---|---|
| −40 °C | −40 °F | Where the scales meet |
| 0 °C | 32 °F | Water freezes |
| 20 °C | 68 °F | Room temperature |
| 37 °C | 98.6 °F | Body temperature |
| 100 °C | 212 °F | Water boils |
| 160 °C | 320 °F | Fan oven, moderate |
| 180 °C | 356 °F | Cakes and biscuits |
| 220 °C | 428 °F | Bread and pizza |
Worked examples
- 200 °C × 9 ÷ 5 + 32 = 392 °F, a hot oven for pizza.
- 160 °C is 320 °F, the fan-oven setting for a moderate bake.
- 38.5 °C is 101.3 °F, a mild fever.
Checking the answer by hand
Double the Celsius figure, subtract 10% of it, then add 32. For 180 °C: double gives 360, minus 36 is 324, plus 32 is 356 °F — exact. If your estimate is off by more than a couple of degrees, you added 32 before multiplying.
Common mistakes
- Adding 32 before multiplying by 9/5. Doing it in the wrong order overstates the answer by 32 °F.
- Converting a temperature difference with the absolute formula. A 10 °C rise is 18 °F, not 50 °F.
- Forgetting that a fan oven needs about 20 °C less than the conventional figure, even after a correct conversion.
A last check on the Celsius table: −40 °C −40 °F sits at the base of the chart, and the rows above it step in the same proportion, so you can scale from that first row instead of reading every line. If a figure you were quoted falls between two rows, it is the Fahrenheit side that has been rounded, not the conversion itself.
