Frequently asked questions
What gas mark is 180 C?
180 C is gas mark 4, a moderate oven often used for cakes and bakes. In Fahrenheit that is 356 F, which most recipes round to 350 F.
How do I convert Celsius to Fahrenheit for an oven?
Multiply the Celsius value by 9/5 and add 32. So 200 C becomes 200 times 1.8 plus 32, which is 392 F, usually written as 400 F on dials.
What is the gas mark scale?
Gas mark numbers run from 1 to 9, where gas 1 is about 140 C and each step adds roughly 10 to 15 C. Gas 4 is a moderate oven and gas 7 is hot.
Why is there no gas mark for low temperatures?
The standard gas mark scale starts at gas 1, about 140 C. Cooler settings below roughly 135 C sit under gas 1, so no whole gas mark is shown.
Are the conversions exact?
Celsius and Fahrenheit convert exactly with the standard formula. Gas marks map to the nearest mark on the common UK oven chart, so they round.
