Free Oven Temperature Converter — °F, °C & Gas Mark
A British recipe says Gas Mark 4, your American oven dial says Fahrenheit, and the European cookbook says 180°C — same oven, three languages. Type any temperature and get all three instantly, the nearest Gas Mark, an optional fan-oven adjustment, and a cheat sheet of the settings recipes actually use. No ads to scroll past while your hands are covered in flour.

How it works
Conversions use the exact formulas (°C = (°F − 32) × 5/9) and a standard Gas Mark table anchored at Gas Mark 1 = 140°C / 275°F, with each mark adding roughly 10°C. The fan toggle applies the common rule of thumb — set a convection oven about 20°F (10°C) lower than the conventional temperature for the same result.

Frequently asked questions
Is Gas Mark 4 really 350°F?
Yes — Gas Mark 4 is 180°C in many modern tables and 350°F; you will see 175–180°C both used. For most baking the difference is negligible.
Why do fan ovens cook cooler?
The fan circulates hot air so heat reaches food more efficiently; the lower setting compensates so food does not over-brown.
What temperature is “moderate oven” in old recipes?
Moderate means about 350°F / 175°C / Gas Mark 4. “Slow” is ~300°F, “hot” is ~425°F.
