Oven Temperature Converter
Convert recipe oven temperatures without rounding away useful precision.
Gas marks are shown as the nearest common setting. Oven calibration and fan-assisted settings vary.
Quick answer
Use Fahrenheit = Celsius × 9/5 + 32 and Celsius = (Fahrenheit − 32) × 5/9. Gas marks are practical nearest settings.
Temperature formulas
Celsius = (Fahrenheit − 32) × 5/9. Fahrenheit = Celsius × 9/5 + 32. Gas mark results use the nearest common oven setting.
Common oven temperatures
| Fahrenheit | Celsius and Gas Mark |
|---|---|
| 300°F | 149°C (Gas Mark 2) |
| 325°F | 163°C (Gas Mark 3) |
| 350°F | 177°C (Gas Mark 4) |
| 375°F | 191°C (Gas Mark 5) |
| 400°F | 204°C (Gas Mark 6) |
| 425°F | 218°C (Gas Mark 7) |
| 450°F | 232°C (Gas Mark 8) |
Practical examples
- 350°F = about 177°C = Gas Mark 4.
- 400°F = about 204°C = Gas Mark 6.
- 450°F = about 232°C = Gas Mark 8.
Measurement notes
Oven calibration, fan-assisted settings, rack position, and cookware can change real cooking conditions. Check food doneness rather than relying only on time.
Common question
Are gas marks exact temperature settings?
Gas marks are common practical oven settings. This calculator returns the nearest setting because ovens and regional conventions can vary.
