What is 180°C in Fahrenheit?
180°C conventional is 356°F. Many recipe charts round this to 350°F because domestic ovens are usually set in larger increments.

These are standard approximate cooking conversions. The fan column follows the common guideline of setting a fan oven 20°C lower than a conventional oven.
| Conventional | Fan oven | Fahrenheit | Gas mark | Typical description |
|---|---|---|---|---|
| 110°C | 90°C | 230°F | ¼ | Very cool |
| 130°C | 110°C | 266°F | ½ | Very cool |
| 140°C | 120°C | 284°F | 1 | Cool |
| 150°C | 130°C | 302°F | 2 | Cool |
| 170°C | 150°C | 338°F | 3 | Moderate |
| 180°C | 160°C | 356°F | 4 | Moderate |
| 190°C | 170°C | 374°F | 5 | Moderately hot |
| 200°C | 180°C | 392°F | 6 | Hot |
| 220°C | 200°C | 428°F | 7 | Hot |
| 230°C | 210°C | 446°F | 8 | Very hot |
| 240°C | 220°C | 464°F | 9 | Very hot |
Celsius and Fahrenheit use a precise mathematical conversion: °F = (°C × 9 ÷ 5) + 32. Fan ovens circulate hot air, so recipes commonly reduce the conventional setting by about 20°C.
Gas marks are different. They are stepped settings rather than a continuous temperature scale, so this converter uses a fixed lookup table and reports the nearest standard mark.
Ovens cycle above and below their set temperature, and calibration, shelf position, cookware, and airflow all affect cooking. An inexpensive oven thermometer can help you understand how your own appliance behaves.

A common guideline is to reduce a 180°C conventional oven setting to 160°C for a fan oven.
Gas Mark 4 is approximately 180°C conventional, 160°C fan, or 356°F.
No. Conversions are useful approximations, and real oven temperatures vary. Follow the recipe and appliance guidance, and check food for doneness.
