How to Use This Converter

Enter a temperature, pick its unit, and get every other oven scale at once — plus a plain-English description of how hot that is.

Type 180 in °C to see it equals 356°F and Gas Mark 4.
Choose Gas Mark to convert British recipes into Celsius or Fahrenheit.
The fan setting tells you what to dial if you own a convection oven.

Frequently Asked Questions

Why is my fan oven different?

Convection fans circulate hot air, cooking food faster and more evenly. Recipes written for conventional ovens usually need the temperature dropped by about 20°C.

What is a Gas Mark?

Gas Mark is a scale used in British cookers, from Gas Mark 1 (140°C / 275°F) up through Gas Mark 9 (240°C / 475°F).

Does oven type change baking time?

Yes. A fan oven can reduce baking time by roughly 10–20% alongside the lower temperature. Start checking earlier.

What is a moderate oven?

Around 180°C / 350°F / Gas Mark 4 — the most common setting for cakes and casseroles.

Practical Example

A British recipe asks for Gas Mark 5. Convert it:

Gas Mark 5 ≈ 190°C = 375°F
Fan oven setting ≈ 170°C
Description: Moderately hot — good for roasts and bread.
