180°C to Fahrenheit

180°C is 356°F exactly — and in recipes, 180°C and 350°F are the same setting (gas mark 4).

180°C in Fahrenheit

356°F

recipes use 350°F · gas mark 4 · fan 160°C

Data & method: Exact °F ↔ °C maths (NIST); gas marks and recipe pairings from the standard UK gas-mark table; fan = conventional − 20 °C (Which? conversion table, Hoover UK); US convection = −25 °F (LG). Your oven's manual overrides any rule of thumb. The calculations are covered by automated tests. How we calculate →

Recipe says 180°C fan?

With a fan oven, set 180°C as written. In a conventional (non-fan) oven, add 20°C: set 200°C — 392°F exactly, paired with 400°F in recipes, gas mark 6.

180°C — all four oven scales

The exact conversion is °C × 9/5 + 32, so 180°C works out to 356°F. Recipe writers don't use the exact figure: the long-standing pairing puts 180°C alongside 350°F and gas mark 4, and published conversion charts (Which?'s among them) treat the paired values as the same setting. Follow whichever scale your dial shows.

For a conventional recipe in a fan (convection) oven, use 160°C — the standard UK adjustment is conventional minus 20°C (a 36°F difference), because moving air transfers heat faster than still air; the oven isn't hotter than its dial, it just cooks faster at the same setting. Hoover also says long cooking times can be shortened by up to 10 minutes per cooking hour — check the food is cooked. Bake times are otherwise unaffected by converting between scales: 180°C and 350°F are the same setting.

What bakes at this temperature

350°F / 180°C is the territory of everyday cakes, brownies and cookies — the default baking temperature. Home ovens cycle above and below their set point and many run hot or cold from the factory — a standalone oven thermometer on the middle rack tells you more than any conversion chart can.

Frequently Asked Questions

What is 180°C in Fahrenheit for an oven?

180°C equals 356°F exactly (°C × 9/5 + 32). In practice recipes treat 180°C and 350°F as the same setting — that's the published gas-mark-table pairing (gas mark 4).

What is 180°C fan in Fahrenheit?

If a recipe says 180°C fan and your oven is a fan oven, set 180°C. In a conventional oven, add 20°C: 200°C, which is 392°F exactly (400°F on a 25°F dial, gas mark 6).

What is 180°C in a fan (convection) oven?

For a conventional recipe at 180°C, use 160°C in a fan oven — the standard UK adjustment is conventional minus 20°C, because circulating air transfers heat faster than still air. Your oven's manual overrides the rule of thumb.

What gas mark is 180°C?

180°C corresponds to gas mark 4, described as a moderate oven.

What bakes at 180°C?

180°C (350°F) is the territory of everyday cakes, brownies and cookies — the default baking temperature. Bake times don't change when you convert the temperature — only the fan adjustment changes how fast things cook.
