About This Tool

Recipes come from everywhere โ€” American cookbooks use Fahrenheit, European ones use Celsius, British recipes still reference Gas Mark numbers, and fan (convection) ovens need a lower temperature than conventional ones. This converter handles all four systems in one place so you never have to guess or Google "350 F to C" again. Type a temperature into any field and the other three update instantly. The converter shows both the exact mathematical result and the recipe-friendly rounded value that cookbooks actually use. For example, 350ยฐF converts to exactly 176.67ยฐC, but every recipe rounds that to 180ยฐC โ€” this tool shows you both so you know exactly what to set your oven to. Fan ovens (convection ovens) circulate hot air, so they cook more efficiently and need a lower temperature โ€” typically 20ยฐC (about 25ยฐF) less than a conventional oven. If your recipe says 200ยฐC but you have a fan oven, set it to 180ยฐC. This converter does that math automatically.

How to Use

1. Click a preset button (e.g., "Baking Cake 350ยฐF") for instant conversion, or type directly into any field 2. Enter a temperature in any of the four fields โ€” Fahrenheit, Celsius, Gas Mark, or Fan Oven ยฐC 3. All other fields update instantly with both exact and recipe-rounded values 4. Check the status bar below the inputs for a quick summary with the oven description 5. Scroll down to the Gas Mark reference table โ€” click any row to load it into the converter 6.

Formula

Fahrenheit to Celsius: ยฐC = (ยฐF โˆ’ 32) ร— 5/9 Celsius to Fahrenheit: ยฐF = (ยฐC ร— 9/5) + 32 Gas Mark to Fahrenheit: ยฐF = (Gas Mark ร— 25) + 250 (for GM 1-10) Special cases: Gas Mark ยผ = 225ยฐF, Gas Mark ยฝ = 250ยฐF Fan Oven (convection): Fan ยฐC = Conventional ยฐC โˆ’ 20 Recipe rounding: Nearest 5ยฐC below 200ยฐC, nearest 10ยฐC at 200ยฐC and above

Frequently Asked Questions

What is 350ยฐF in Celsius?
350ยฐF equals 176.67ยฐC exactly, but recipes round this to 180ยฐC. This is the most common baking temperature โ€” used for cakes, cookies, casseroles, and many everyday recipes. If you have a fan (convection) oven, set it to 160ยฐC instead.
What is Gas Mark 4 in Celsius and Fahrenheit?
Gas Mark 4 equals 350ยฐF or 180ยฐC (rounded for recipes). This is described as a 'Moderate' oven and is the standard baking temperature for cakes, biscuits, and casseroles. In a fan oven, use 160ยฐC for the same result.
What is the difference between a fan oven and a conventional oven?
A fan oven (also called convection oven) has a fan that circulates hot air around the food, cooking it more evenly and efficiently. Because of this, fan ovens cook at a lower temperature โ€” typically 20ยฐC (about 25ยฐF) less than a conventional oven. If a recipe says 200ยฐC conventional, set your fan oven to 180ยฐC. Most modern ovens have both conventional and fan settings.
What is a moderate oven temperature?
A 'moderate' oven is 350ยฐF / 180ยฐC / Gas Mark 4. This is the most commonly used oven temperature in cooking. Recipes that call for a 'moderate' or 'medium' oven mean this temperature. Below moderate: 'slow' or 'low' is 275-325ยฐF (140-160ยฐC). Above moderate: 'hot' is 400-450ยฐF (200-230ยฐC).
What temperature do you cook pizza at?
Homemade pizza bakes best at 475-500ยฐF (245-260ยฐC / Gas Mark 9) โ€” as hot as your home oven goes. Professional Neapolitan pizza ovens reach 800-900ยฐF (430-480ยฐC). At home, preheat your oven to maximum for at least 30 minutes. Use a pizza stone or steel on the lowest rack for the crispiest base.
What are all the Gas Mark values in Celsius and Fahrenheit?
Gas Mark ยผ = 225ยฐF / 110ยฐC (Very Slow), GM ยฝ = 250ยฐF / 120ยฐC (Very Slow), GM 1 = 275ยฐF / 140ยฐC (Slow), GM 2 = 300ยฐF / 150ยฐC (Slow), GM 3 = 325ยฐF / 160ยฐC (Moderately Slow), GM 4 = 350ยฐF / 180ยฐC (Moderate), GM 5 = 375ยฐF / 190ยฐC (Moderately Hot), GM 6 = 400ยฐF / 200ยฐC (Hot), GM 7 = 425ยฐF / 220ยฐC (Hot), GM 8 = 450ยฐF / 230ยฐC (Very Hot), GM 9 = 475ยฐF / 240ยฐC (Very Hot), GM 10 = 500ยฐF / 260ยฐC (Extremely Hot).
Why do recipes round Celsius temperatures?
Exact conversions produce awkward decimals โ€” 350ยฐF is really 176.67ยฐC. Recipes round to the nearest 5 or 10 degrees because oven thermostats aren't precise enough for the exact value to matter. A difference of 3-5ยฐC has no noticeable effect on cooking. This converter shows both the exact value and the rounded recipe value so you can see what cookbooks use.
