How to use it
- Type the temperature from your recipe, or tap one of the common settings.
- Choose whether you entered °F, °C or a gas mark.
- Read the exact conversion, the nearest gas mark and the usual rounded dial setting.
Oven dials are often off by several degrees. An inexpensive oven thermometer shows what your oven is really doing.

Frequently asked questions
What is 350°F in Celsius?
350°F is 177°C. Recipes usually round it to 180°C, and it is gas mark 4.
What is 180°C in Fahrenheit?
180°C is 356°F. On a US oven, set 350°F.
How do I adjust for a convection or fan oven?
Many recipes suggest lowering the temperature by about 25°F (around 15–20°C) for convection, or checking for doneness earlier. Your oven’s manual is the best guide.
What is a gas mark?
It’s the temperature scale on many UK gas ovens. Gas mark 4 is about 350°F (180°C); each step up adds roughly 25°F.
Why does my food bake faster or slower than the recipe says?
Oven thermostats drift, and dark pans, glass dishes and rack position all change how food bakes. An oven thermometer helps you see whether the oven itself is the cause.
