What 300°F is used for

Cool oven

300°F is Gas Mark 2 (about 150°C). It is a slow oven for long, gentle cooking such as rich fruit cakes and slow-roast meat.

Typical uses at this heat: slow roasts, pavlova, rich fruit cake.

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

How to convert 300°F to °C

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

300 − 32 = 268
268 × 5 ÷ 9 = 148.9°C

UK oven dials go up in 10°C steps, so recipes round this to 150°C.
