Oven Temperature Chart
British recipes still quote gas marks; American cards use °F; European boxes list °C — often with “fan” in small print. Pick your starting scale, get gas mark and both temperatures, then check whether you need a fan or conventional equivalent before you preheat.

Fan vs conventional
Many UK and EU cards say “180°C fan” or “200°C conventional.” The usual shortcut is about 20°C lower on fan for the same bake.
If your recipe is fan / convection
180°C / 356°F
Try on a conventional (no fan) oven
200°C / 392°F
Common fan ↔ conventional pairs
| Fan / convection | Conventional | |
|---|---|---|
| 150°C | 170°C | 338°F |
| 160°C | 180°C | 356°F |
| 170°C | 190°C | 374°F |
| 180°C | 200°C | 392°F |
| 190°C | 210°C | 410°F |
| 200°C | 220°C | 428°F |
| 220°C | 240°C | 464°F |

When to use this chart
You found “Gas 6” on a handwritten sponge recipe but your rental oven only shows Fahrenheit. Or the box says “200°C (180°C fan)” and you are not sure which number to trust. This page is for dial and card translation — not for lowering heat when moving to an air fryer (that needs time changes too).
For a simple °C ↔ °F swap without gas or fan context, the Celsius to Fahrenheit converter stays quicker. For basket appliances, use the air fryer conversion calculator.

FAQ
- What is gas mark 4 in Fahrenheit?
- Gas mark 4 is about 180°C / 350°F on most UK charts — the band used for many cakes and cookies. Your cooker may run hot or cool; use an oven thermometer if edges brown too fast.
- How do I convert 180°C fan to a conventional oven?
- A common rule is to add about 20°C when moving from fan to conventional for the same bake — so 180°C fan ≈ 200°C conventional (about 400°F). Fan circulates heat faster, so recipes often list a lower fan temperature.
- Is gas mark the same as a Fahrenheit oven dial?
- Gas marks label gas ovens (UK/Ireland). Electric and US ovens usually show °F or °C only. Use the gas mark column in our chart to find the nearest °F or °C setting on your dial.
- How is this different from the Celsius to Fahrenheit converter?
- The Celsius to Fahrenheit page is a straight scale swap. This page adds gas mark lookup, nearest-mark matching for arbitrary °C/°F, and fan vs conventional pairs — built for oven recipe cards, not candy thermometers.
