Frequently Asked Questions

What is 300°F in Celsius?

300 degrees Fahrenheit equals 148.89°C.

What Is 300°F Used For?

300°F (148.89°C) is a common oven temperature for slow cooking, drying meringues, warming bread, and dehydrating fruits. Understanding when to use 300 degrees Fahrenheit helps you follow recipes accurately, especially when converting between US and European cooking instructions.

FoodApproximate Cook Time at 300°F
Meringues60–90 minutes
Slow-roasted garlic45–60 minutes
Warming bread rolls10–15 minutes
Slow-cooked pulled pork4–6 hours

What Is 300°F in Gas Mark?

300°F (148.89°C) is approximately Gas Mark 2. Gas marks are used in older British recipes and on some European ovens.

What Is 300°F in a Fan Oven?

For a fan-assisted (convection) oven, reduce the temperature by 25°F. So 300°F in a conventional oven becomes approximately 275°F (135°C) in a fan oven. Fan ovens circulate air and cook food faster and more evenly.

Is 300°F the Same as 150°C?

300°F equals 148.89°C, which is close to but not exactly 150°C. Most recipe conversions round the value for simplicity — in practice, the difference is small enough that it rarely affects cooking results.

300 f to c (149°C) is used for slow-cooked meats, custards, and drying fruit. At 300 f to c, tough cuts of meat break down over several hours into tender, shreddable portions. For reference, see the BBC Good Food oven temperature guide.
