Oven Temperature Converter
The internet's recipes travel, but ovens don't: American recipes speak Fahrenheit, European ones Celsius, and British vintage cookery writes gas marks. Enter any setting in one system and this converter gives the equivalent in both others — plus the full reference table from 275°F meringue-land to 500°F pizza-blast, so you can sanity-check any recipe at a glance.
The table's fourth column is the practical one: what each temperature is actually used for, from slow-roasting to fast browning. One warning is built into the page: fan (convection) ovens run about 20°C hotter than these conventional settings — subtract 20°C or one gas mark equivalent when the manual says fan-assisted.
How to use
- Pick the unit your recipe uses — °F, °C or gas mark — and type the temperature.
- Read the equivalent in both other systems in the big result, with the nearest gas mark named.
- Scan the reference table for the typical use at each setting, and share the conversion with one tap.
Frequently asked questions
What is 350°F in Celsius and gas mark?
350°F is 175°C — gas mark 4, the workhorse of baking (cookies, cakes, most roasting). It is the single most common oven setting in American recipes, which is why it anchors the middle of the reference table.
How do gas marks convert to Celsius?
Gas mark 1 is about 140°C and each mark adds roughly 13-15°C (250°F + 25°F per mark in Fahrenheit). The converter rounds to the nearest mark because dials are that imprecise anyway — anything within a quarter-mark is the same oven reality.
Do I need to adjust for a fan oven?
Yes — fan-assisted ovens circulate heat and effectively cook 20°C (25°F) hotter than conventional settings. Reduce the temperature by 20°C (or one gas mark equivalent) or shorten the time; when a recipe says 180°C conventional, run a fan oven at 160°C.
Why do recipes disagree about temperatures?
Ovens lie: a dial reading 180°C can sit 15°C off true, and hot spots vary by rack. The converter gives you the correct target — after that, an oven thermometer is the cheapest baking upgrade there is, because you calibrate your oven against the number the recipe means.
