    350 °F is closest to gas mark 4 (350 °F).

Informazioni su Oven temperature and pan size converter

Oven temperatures convert with °F = °C × 9/5 + 32. A fan oven is set about 20 °C below a conventional one, and gas mark 1 is 275 °F (140 °C), with each mark adding 25 °F. For pans, the ingredient factor is the area of your pan divided by the area of the recipe's pan, which keeps the batter at the same depth.

The default converts 350 °F: 176.7 °C, which recipes round to 180 °C, or 156.7 °C in a fan oven (usually written 160 °C), and gas mark 4. In pan mode, a 9-inch round pan (63.6 sq in) and an 8-inch square pan (64 sq in) hold almost the same amount, a factor of 1.006.

Oven thermostats and fans vary, so treat the converted setting as a starting point. When batter ends up deeper or shallower than the recipe intended, check for doneness early.

Domande

What is 180 °C in Fahrenheit?

356 °F, from 180 × 9/5 + 32. Recipes round it to 350 °F, which is gas mark 4, and the Which? oven conversion table puts 180 °C, 160 °C fan, 350 °F and gas mark 4 on the same row. Going the other way, 350 °F is exactly 176.7 °C.

How much lower should a fan oven be?

About 20 °C lower than the conventional temperature, according to Which?, so 180 °C becomes 160 °C fan and 200 °C becomes 180 °C fan. The fan moves hot air over the food, and leaving the setting unchanged can cook the outside too quickly. Oven makers' manuals give the figure for a specific model.

What temperature is gas mark 4?

180 °C (350 °F), or 160 °C in a fan oven. Gas mark 1 is 140 °C (275 °F) and each mark adds 25 °F, about 14 °C: gas 6 is 200 °C (400 °F) and gas 9 is 240 °C (475 °F), as listed in the Which? table. The Celsius values are rounded to the nearest 10 °C.

Can I use an 8-inch square pan instead of a 9-inch round one?

Yes. A 9-inch round pan has an area of π × 4.5² = 63.6 square inches and an 8-inch square pan has 64, so the recipe needs no change. A 9 × 13 inch pan has 117 square inches, 1.84 times the 9-inch round, so batter for the rectangle fills nearly two round pans to the same depth.

How do you adjust a recipe for a different cake tin?

Multiply every ingredient by the new tin's area divided by the old tin's area. For round tins that is the ratio of the diameters squared: moving from a 20 cm to a 23 cm tin is (23 ÷ 20)² = 1.32, so use about a third more of everything. The batter then sits at the same depth, so the baking time stays close to the original.

Quanto è preciso «Oven temperature and pan size converter»?

La precisione dipende dai dati inseriti e dalle ipotesi del metodo. Il calcolo decimale usa 50 cifre significative, ma stime, metodi numerici e dati di origine possono essere meno precisi; l’arrotondamento visualizzato non elimina questi limiti. Esempi svolti verificati con fonti indipendenti: 9. Per esempio, «350 °F → °C» viene verificato con Python decimal: (350 − 32) × 5/9; gas mark 4 = 350 °F (gas mark table).

Da dove proviene il metodo?

Gas mark — conversion table (1 = 275 °F, +25 °F per mark); Which? — Oven temperature conversion table (fan ovens 20 °C lower).
