What 250°F is used for

Cool oven

250°F is Gas Mark ½ (UK charts say 120°C). It is a low, slow setting used for drying, meringues and very slow roasting.

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 250°F to °C

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

250 − 32 = 218
218 × 5 ÷ 9 = 121.1°C

UK oven dials go up in 10°C steps, so recipes round this to 120°C.

Common questions

What is 250°F in Celsius?

250°F is 121.1°C. UK recipes and oven dials round it to 120°C.

What Gas Mark is 250°F?

250°F is Gas Mark ½.

What is 250°F in a fan or convection oven?

In a US convection oven, use 225°F (25°F lower). In a UK fan oven, use 100°C. Many newer US ovens subtract the 25°F automatically in convection mode, so check your manual before you reduce it twice.

Is 250°F hot?

250°F (121°C) counts as a cool oven. Typical uses: slow roasts, pavlova, rich fruit cake.
