Frequently asked questions
What is Gas Mark 4 in Celsius and Fahrenheit?
180°C, which converts to 356°F exactly (though many recipe charts round this to the conventional 350°F pairing) - Gas Mark 4 is one of the most common baking temperatures, standard for cakes and general baking in UK recipes.
What is 200°C in Gas Mark?
Gas Mark 6 - 200°C is a common temperature for roasting.
Why does Gas Mark use fractions like 1/4 and 1/2 at the low end?
Gas Mark's lowest settings (1/4 and 1/2, corresponding to 110°C/225°F and 120°C/250°F) are used for very low, slow cooking like meringues or slow roasts, and the fractional notation is a historical convention from the original UK gas oven dial markings.
Is Gas Mark still used today?
Mostly in older UK recipes and some British cookbooks - most modern ovens, including in the UK, use Celsius directly, but Gas Mark conversions are still commonly included for compatibility with older recipes and gas ovens that still use the dial system.
What is 350°F in Celsius?
About 177°C, though most recipes and oven dials round this to 180°C - the exact formula is (350 - 32) × 5/9 ≈ 176.7°C.
Why do converted oven temperatures often get rounded to values like 180°C instead of the exact math?
Oven dials and recipe conventions use round, memorable numbers (180°C, 200°C, 220°C) rather than exact converted decimals, since ovens rarely hold temperature that precisely anyway - a couple of degrees of rounding has no practical effect on baking results.
Is 'oven temperature converter' the same thing as a 'gas mark to celsius converter'?
Yes - gas mark is just one of the temperature scales this tool converts, alongside Celsius and Fahrenheit, so searching for a gas-mark-specific converter and using this general oven temperature converter get you the same result.
