🔥 Oven Temperature Converter
Convert oven temperatures between Celsius, Fahrenheit, and Gas Mark.
Nothing ruins a Sunday baking project quite like realizing the glorious British cake recipe you are following specifies “Gas Mark 4” while your oven only shows Celsius. This oven temperature converter handles the three most common oven scales — Celsius (°C), Fahrenheit (°F), and Gas Mark — so you can bake with confidence no matter where your recipe comes from.
Imagine you have found a perfect sourdough recipe from an American blog that says “bake at 425°F.” Your European oven is set in Celsius. Enter 425, select Fahrenheit as the source and Celsius as the target, and you will instantly see that 425°F equals about 218°C. Or perhaps you are adapting a classic Mary Berry recipe that calls for Gas Mark 5 — that translates to 190°C or 374°F, perfect for a golden sponge cake.
The Gas Mark system is still widely used in the UK and in older British cookbooks. It runs from ¼ (very low, about 120°C) up to 10 (extremely hot, about 260°C). The converter intelligently maps to the nearest standard Gas Mark setting, so you always get a practical result you can actually set on your oven dial. No more squinting at tiny conversion charts stuck to the inside of a kitchen cupboard.
Whether you are roasting vegetables, baking bread, or slow-cooking a casserole, getting the temperature right is the single most important factor in oven cooking. Bookmark this converter and spare yourself the burnt edges and raw centers that come from guessing the conversion.
Frequently Asked Questions
What is Gas Mark 4 in Celsius and Fahrenheit?
Gas Mark 4 equals 180°C (356°F). This is one of the most commonly used oven settings and is perfect for baking cakes, cookies, and roasting vegetables. Gas Mark 4 is often described as a "moderate" oven in British recipes.
How do I convert 350°F to Celsius?
350°F is approximately 177°C. The exact formula is (°F - 32) × 5/9. Many recipes round this to 175°C or 180°C depending on the oven. 350°F is the standard American baking temperature and corresponds roughly to Gas Mark 4.
What is the difference between a fan oven and a conventional oven?
Fan ovens (also called convection ovens) circulate hot air, cooking food more evenly and typically requiring a temperature 20°C (about 35°F) lower than conventional ovens. If a recipe was written for a conventional oven, reduce the temperature by 20°C when using a fan oven. This converter does not account for fan vs. conventional — adjust manually based on your oven type.
Why do British recipes use Gas Mark instead of Celsius?
The Gas Mark system originated with gas ovens in the UK, where temperature dials were marked with numbered settings rather than degree values. The system became a cultural standard, still used by beloved British cookbook authors like Delia Smith and Mary Berry. Though modern digital ovens show Celsius, many home cooks continue to use Gas Mark out of habit and tradition.
