Oven Temperature Converter

180 C is gas mark 4, a moderate oven used for many cakes and bakes. In Fahrenheit that works out to 356 F, which most recipes simply round to 350 F on the dial.

Multiply the Celsius figure by 9/5 and add 32. So 200 C becomes 200 times 1.8 plus 32, which is 392 F, usually printed as 400 F. This converter uses the exact formula, then the recipe rounds it.

Gas marks run from 1 to 9 on many British ovens. Gas 1 is about 140 C and each step up adds roughly 10 to 15 C. Gas 4 is a moderate oven, gas 6 is moderately hot, and gas 7 and above are hot.

The standard chart starts at gas 1, around 140 C. Anything cooler than roughly 135 C sits below gas 1, so the tool shows Below scale rather than invent a fractional mark. Slow-cook and dehydrate settings often fall here.

Celsius and Fahrenheit convert exactly with the standard formula and are then rounded to whole degrees. Gas marks snap to the nearest whole mark on the common UK chart, so they are the closest match rather than a precise formula.

Usually yes, by about 20 C or 25 F, but this converter does not apply that adjustment. It converts between units at face value. Drop the converted number yourself if your recipe was written for a conventional oven.

Older recipes name a heat rather than a number. This tool labels the setting from the Celsius value: cool below 120, low around 150 to 170, moderate near 180, and hot from about 210 upward, matching traditional recipe language.

A few gas mark charts exist and they disagree by a few degrees, especially at the ends. This tool follows the widely used UK table where gas 4 is 180 C and gas 6 is 200 C, which suits most modern recipes.

No. Gas marks are converted as whole numbers from 1 to 9, since that is how oven dials are marked. Pick the nearest whole mark, or switch to Celsius for a finer setting.
