Oven Temperature Converter

Gas vs. electric ovens

For temperature conversion purposes, gas and electric ovens use the same scale.180°C means 180°C in both. The differences between them are operational, not numerical. Gas ovens introduce moisture as a byproduct of combustion, which can produce softer crusts. They tend to heat from the bottom and can have hot spots, particularly near the burner.

Electric ovens.especially those with both top and bottom elements.tend to be more even. Convection (fan-assisted) electric ovens are the most consistent of all. For baking bread and pastry, electric ovens with a fan give the most predictable results.

If your recipes are coming out unevenly browned, rotate the pan halfway through baking regardless of oven type. Hot spots exist in virtually every domestic oven.the dial temperature and the actual internal temperature are rarely identical.

Fan and convection ovens

A fan (convection) oven circulates hot air around the food. This transfers heat more efficiently than a static oven, which means the same temperature setting cooks food faster and more evenly. The standard adjustment is to reduce the conventional temperature by 20°C (35°F), or reduce baking time by 10–15% at the same temperature.

Most modern published recipes, particularly from the UK and Australia, are written for fan ovens. American recipes are almost always written for conventional (static) ovens. When in doubt, check whether the author specifies "fan" or "fan-forced". If they don't, assume conventional. Apply the 20°C reduction if your oven defaults to fan mode.

For bread with a thick crust (sourdough, baguettes), conventional mode is often preferred.the steam stays around the bread longer, which helps oven spring and crust development. For cookies, tarts, and anything you want evenly golden, fan mode wins.

Gas mark explained

Gas Mark is a temperature scale developed for gas ovens in the UK, where it remains standard in older recipes and much home cooking. The scale runs from ¼ (about 110°C / 225°F) to 9 (240°C / 475°F). Gas Mark 4.180°C / 350°F.is the most commonly used setting and corresponds to a moderate oven suitable for most cakes.

The Gas Mark system isn't perfectly linear. Different manufacturers implement it slightly differently. Gas Mark 1 is roughly 140°C, and each additional mark adds about 10–14°C. The reference table uses the traditional culinary standard, not any single manufacturer's calibration.

Baking temperatures by type

Very slow (120–150°C / 250–300°F). Meringues, pavlova, drying fruit, keeping food warm. At these temperatures you're evaporating moisture without browning.

Slow (150–170°C / 300–340°F). Dense fruit cakes, rich puddings, long-cook custards. Low heat prevents the outside from overcooking before the centre sets.

Moderate (170–190°C / 340–375°F). Most cakes, muffins, cookies, quick breads, loaf cakes. The most common range for everyday baking.

Moderately hot (190–210°C / 375–410°F). Sourdough, enriched breads, most yeasted loaves. Hot enough for good oven spring and crust development.

Hot (210–230°C / 410–450°F). Focaccia, high-hydration breads, home-oven pizza. The upper limit of most domestic ovens.

Very hot (230°C+ / 450°F+). Detroit pizza, high-heat bread baking, anything that needs a quick, aggressive crust. True Neapolitan pizza requires 450°C+ and is only achievable in a dedicated wood-fired oven.

Why oven temperatures lie

Consumer ovens are not precision instruments. Studies have found that domestic ovens can run 10–30°C (20–55°F) hotter or colder than their dial setting, and the temperature cycles throughout baking.typically ±10–15°C around the set point. This is why two bakers following the same recipe in different kitchens can get different results.

An oven thermometer is the single most useful piece of kit for consistent baking. A basic one costs a few pounds or dollars and will immediately tell you whether your oven runs hot or cold. Calibrate once, remember the offset, and adjust your dial accordingly. Most problems blamed on recipes are actually oven calibration problems.

Position also matters. The top of most ovens is hotter than the bottom, and the centre of most ovens is hotter than the edges. A middle rack and rotating the pan halfway through baking eliminates most of this variability.
