What 550°F is used for

Extremely hot

550°F (287.8°C) is the highest setting on many American home ovens. It is far beyond the gas mark scale and is used for pizza.

Typical uses at this heat: pizza at your oven’s maximum; few recipes go this high.

Oven dials can be out by a surprising amount. Here’s how to check yours with an oven thermometer.

How to convert 550°F to °C

Subtract 32, then multiply by 5 and divide by 9:

550 − 32 = 518
518 × 5 ÷ 9 = 287.8°C

UK oven dials go up in 10°C steps, so recipes round this to 290°C.
