Convert any oven temperature in seconds
Enter a temperature in Celsius, Fahrenheit, gas mark or fan (convection) and instantly see it in all four. Recipes from different countries use different scales — UK recipes often use gas marks, US recipes use Fahrenheit, and most of the world uses Celsius — so a quick conversion prevents over- or under-cooking. A fan oven runs hotter for the same dial setting, so the rule of thumb is to set it about 20°C lower than a conventional oven; this tool makes that adjustment for you.
Celsius, Fahrenheit, gas mark and fan
The conversions here use exact arithmetic: °F = °C × 9/5 + 32, and the fan temperature is 20°C below the conventional temperature. Recipe books usually round these to tidy numbers — for example 180°C is printed as “350°F / gas mark 4” even though the exact conversion is 356°F. Use the chart below as a quick reference for the most common roasting and baking temperatures.
FAQ
What is gas mark 4 in Celsius? Gas mark 4 is 180°C (356°F), the standard moderate temperature for baking cakes and roasting.
How much lower should a fan oven be set? About 20°C lower than a conventional oven for the same result, or roughly 25°F. So 180°C conventional is about 160°C fan.
Why does my recipe say 350°F for 180°C? Recipes round to convenient numbers. The exact conversion of 180°C is 356°F, but 350°F is close enough for baking and easier to remember.
