Oven temperature converter – convection vs conventional

Many recipes specify temperatures for either convection or conventional ovens. Our converter helps you convert between the two.

The difference

In a convection oven, a fan circulates hot air evenly, providing more uniform heat distribution. This means food cooks faster. The rule of thumb is that convection requires about 20°C lower temperature than conventional.

Gas mark explained

Gas mark is a temperature scale used on British gas ovens. Gas mark 1 equals about 135°C, with each step being about 14°C.

Frequently Asked Questions

Is convection always 20 degrees lower than conventional?

20°C is a good rule of thumb, but it can vary from 15-25°C depending on your specific oven. Newer ovens often have better heat distribution and may require a smaller difference. The best approach is to learn your own oven and consider an oven thermometer.

When should you use convection instead of conventional?

Convection is ideal for cookies, rolls, and dishes where you want even cooking on multiple racks. Conventional (top/bottom heat) is better for cakes, bread, and dishes that need to rise, as the still air provides gentler cooking.

What does gas mark 6 equal in Celsius?

Gas mark 6 equals about 200°C in a conventional oven, or 180°C with convection. It is the most commonly used setting. Other important gas marks: 4 = 180°C, 5 = 190°C, 7 = 220°C.
