Fahrenheit to Celsius Chart
Every ten degrees from 0 to 500 °F, plus the five odd settings recipes quote most — 175, 275, 375, 425 and 475 °F — converted to Celsius with the fan-oven setting beside each row. Ten-degree steps match how oven dials and thermostats are actually marked.
About the Fahrenheit to Celsius Chart
American recipes and weather reports use Fahrenheit, while most of the world uses Celsius, so this chart covers both the freezer-to-oven range and everyday air temperatures. Steps of ten match how oven dials are marked and how weather is usually described.
The formula is (F minus 32) times 5/9. Two anchors make the chart easy to sanity-check: 32 °F is 0 °C (freezing) and 212 °F is 100 °C (boiling). The scales cross at minus 40, where both read the same number.
Fan ovens run about 20 °C cooler than the temperature on a conventional recipe, so a 350 °F instruction becomes 177 °C conventional and about 157 °C on a fan setting. Getting that second step wrong is the most common baking error with converted recipes.
Body temperature sits at 98.6 °F, which is 37 °C, and a fever of 100.4 °F is 38 °C. Those two figures are worth knowing because thermometers in different countries report in different scales.
How the calculation works
- celsius = (fahrenheit − 32) × 5/9
- fan oven = celsius − 20
- 212 °F = 100 °C at sea level

About the Fahrenheit to Celsius Converter
This is the direction US cooks and travellers need most: American recipes, weather forecasts and oven dials are in Fahrenheit, while most of the world reads Celsius. Subtract 32 first, then multiply by 5/9 — doing it in the other order gives an answer that is wrong by 17.8 °C.
For oven temperatures the useful shortcut is that 350 °F ≈ 175 °C and 400 °F ≈ 200 °C. A fan oven should then be set about 20 °C lower than the conventional figure.
How the calculation works
- °C = (°F − 32) × 5/9
- °F = (°C × 9/5) + 32
- 1 °F difference = 0.556 °C difference
Reference values
| Fahrenheit | Celsius | Reference |
|---|---|---|
| 0 °F | −17.8 °C | Very cold, freezer |
| 32 °F | 0 °C | Water freezes |
| 68 °F | 20 °C | Room temperature |
| 98.6 °F | 37 °C | Body temperature |
| 212 °F | 100 °C | Water boils |
| 325 °F | 162.8 °C | Slow oven |
| 350 °F | 176.7 °C | Moderate oven |
| 450 °F | 232.2 °C | Hot oven |
Worked examples
- 400 °F − 32 = 368, × 5 ÷ 9 = 204.4 °C, a hot oven.
- 325 °F is 162.8 °C, the slow oven most sponge recipes use.
- 101 °F is 38.3 °C, a low-grade fever.
Checking the answer by hand
Subtract 32, halve the result, then add about a tenth. For 350 °F: 318, halved 159, plus 16 is 175 °C against an exact 176.7 °C. A result within 2 °C means you subtracted 32 first.
Common mistakes
- Multiplying by 5/9 before subtracting 32, which lands about 17.8 °C off.
- Using 1.8 as a divisor instead of 1.8 as a multiplier. °F = °C × 1.8 + 32, never ÷ 1.8.
- Assuming 350 °F is 180 °C. It is 176.7 °C; the round number is a convention, not a conversion.
Final check. The −40 row is the built-in check, because it is the one temperature where the two scales agree. The other anchors are 32 °F to 0 °C and 212 °F to 100 °C, and no row between them is a simple ratio.
