This converter instantly translates oven temperatures between Fahrenheit, Celsius, and gas mark, and adds a plain-English heat description so you always know how hot your oven actually is.
- Enter the temperature. Type the value from your recipe into the temperature field.
- Select the source unit. Choose Fahrenheit, Celsius, or Gas Mark depending on the unit your recipe uses. Most US recipes use Fahrenheit; most UK and European recipes use Celsius or gas mark.
- Read all three outputs. The result card shows the primary conversion. The breakdown below shows all three scales plus the heat label (for example, Moderate or Hot), so you can verify your oven setting at a glance.
Results update as you type. Use the Share button to send the converted temperature to someone else, or Copy to paste it into a message or notes app.
About Oven Temperature Conversion
Recipe temperature differences between countries are one of the most common reasons home cooks end up with overcooked or undercooked food. A British recipe calling for Gas Mark 4 means the same oven setting as 350°F or 180°C, which is a standard moderate baking temperature for cakes, cookies, and casseroles. An American recipe at 425°F translates to about 220°C or Gas Mark 7, which most ovens label as Hot.
The gas mark scale originates in the UK and is still common in British and Irish cookbooks. Gas Mark 1 is the lowest practical setting (around 275°F / 135°C), and Gas Mark 9 is the highest common setting (around 475°F / 246°C). Some ranges go to Gas Mark 10 (500°F / 260°C). The scale is not perfectly linear, so this converter uses the standard reference table rather than a formula.
The heat descriptions (Cool, Very Slow, Slow, Moderate, Moderately Hot, Hot, Very Hot) are used throughout baking literature as a quick sanity check. If a recipe says to bake at a moderate temperature and your conversion shows Very Hot, something is likely wrong with the original recipe or your conversion.
Frequently Asked Questions
What is 350°F in Celsius and gas mark?
350°F equals approximately 177°C and Gas Mark 4. This is one of the most common baking temperatures, described as Moderate. It is the standard setting for cakes, muffins, cookies, and most casseroles.
What is 180°C in Fahrenheit and gas mark?
180°C equals 356°F, which rounds to Gas Mark 4 in the standard reference table. Most cookbooks treat 180°C and 350°F as interchangeable for everyday baking. The slight difference of 6 degrees has no practical effect on most recipes.
How does gas mark work?
Gas mark is a temperature scale used on gas ovens, primarily in the UK and Ireland. Gas Mark 1 is the lowest setting at roughly 275°F (135°C), and each full mark increases by about 25°F (14°C). Gas Mark 4 (350°F / 177°C) is the most common moderate baking setting. The scale goes up to Gas Mark 9 or 10 on most domestic ovens. There are also fractional marks: Gas Mark 1/4 (225°F) and Gas Mark 1/2 (250°F) for very low and slow cooking.
What oven temperature is considered hot for baking?
Temperatures from 400°F to 425°F (200°C to 220°C, Gas Mark 6 to 7) are considered Hot in standard baking terminology. This range is used for roasting vegetables, baking crusty bread, cooking pizza, and searing meats in the oven. Temperatures above 450°F (230°C, Gas Mark 8) are Very Hot and are used for high-heat roasting and finishing dishes quickly.
