Oven Temperature Converter

The Oven Temperature Converter instantly converts between Fahrenheit, Celsius, and Gas Mark settings for cooking and baking. This is an essential tool for anyone following recipes from different countries, as American recipes typically use Fahrenheit, European and most international recipes use Celsius, and some British recipes reference Gas Mark settings.

Understanding oven temperature conversions is critical for successful cooking and baking. An oven set too hot or too cold can mean the difference between a perfectly golden cake and a burnt or undercooked disaster. The most common oven temperatures range from about 250°F (120°C / Gas Mark 1/2) for slow roasting to 500°F (260°C / Gas Mark 10) for high-heat applications like pizza baking.

The Gas Mark system is a temperature scale used on gas ovens, primarily in the United Kingdom and some Commonwealth countries. Each Gas Mark number corresponds to a specific temperature range. Gas Mark 1 starts at 275°F (135°C), and each subsequent mark increases by 25°F (approximately 14°C). The system was developed in the early 20th century when gas ovens replaced coal ovens and precise temperature controls were not standard.

Common oven temperature reference points include: Gas Mark 3 (325°F / 163°C) for slow baking, Gas Mark 4 (350°F / 177°C) for most cakes and cookies, Gas Mark 5 (375°F / 191°C) for roasting, Gas Mark 6 (400°F / 204°C) for bread and pastries, and Gas Mark 7 (425°F / 218°C) for high-heat roasting. These benchmarks cover the vast majority of standard cooking and baking applications.

This converter accepts input in either Fahrenheit or Celsius and simultaneously outputs all three scales, plus the nearest Gas Mark. Whether you are adapting a French pastry recipe or a classic British roast, the converter ensures your oven is set correctly every time.
