Oven Temperature Conversion Chart (FREE Printable) (2024)

My handy oven temperature conversion chart easily converts Celsius to Fahrenheit to gas marks and vice versa. It quickly answers the most common question: what is 180 C to F oven conversion? 180 C converts to 350 F, and 350 Fahrenheit converts to 180 Celsius.

I created a FREE cheat sheet to help you precisely convert between Fahrenheit, Celsius, and gas mark.

Oven temperature conversion chart: Fahrenheit, Celsius, and Gas Mark

Conventional ovens (traditional ovens) have been the most popular oven type since the 1950s. They come in different sizes with either gas or electric options. Conventional electric ovens have electric heating elements on the top and bottom, while gas ovens rely on a gas flame.

Here are temperature conversion charts for a conventional oven to help convert your recipes into the temperature units of your preference.

Note: the conversions below aren't rounded up or down. You can round the number to the nearest degree; this will have very little to no difference in the result of your recipe.

Some recipes use "slow" or "hot" to describe oven temperatures. Here is a table for approximate temperatures for these terms.

Convert conventional oven to convection oven

Convection ovens (aka fan ovens) differ from conventional ovens: they have fans. The fan circulation of hot air throughout the chamber helps to ensure fast and even cooking of the food.

Interestingly, European convection ovens use a third heating element located behind the fan.

Convection ovens can begas or electric and are sold as an option in stoves, wall ovens, and countertop ovens.

So, how do you adapt a recipe written for a regular oven to work for a convection oven?

• The general rule is to reduce the temperature by 25°F or reduce the cooking time by 25%.
• If you use a fan-assisted gas oven, reduce the gas mark by 1.
• If you use an electric fan oven, you should reduce the temperature by 20°C.

Here is a table to convert the oven temperature (in Fahrenheit) between a conventional oven and a convection one.

And here is another table to convert the oven temperature (in Celsius) between a conventional oven (aka regular oven) and a convection one (aka fan oven).

The best way to succeed in cooking and baking using a convection oven is to check the recommended temperature from the manufacturer's handbook or website. Also, investing in an oven thermometer is a good idea.

Always remember that baked goods might gain a golden brown color quickly due to fan assistant circulation of the hot air.

However, your bakes may not be thoroughly cooked. So make sure to check the doneness of your baking goods.

How to convert Fahrenheit to Celsius

Here is a question: How do we convert the oven temperature from Fahrenheit to Celsius, which is not included in the above charts? There is no problem since there is the equation:

°C = (°F - 32) x 5/9, or °C = (°F - 32) x 0.5556

For example, how to convert 325 Fahrenheit to Celsius:

(325°F - 32) x 0.5556 =162.7908°C, or to round it down, 160°C.

How toconvertCelsiusto Fahrenheit

Here is a formula:

°F = °C (9/5) + 32, or °F = (°C x 1.8) + 32

For example, what is 220 Celsius to Fahrenheit?

(220°C x 1.8) + 32 =428°F, or to round it up 430°F.

How to convert Celsius to Gas Mark

Please use the following formula:

Gas mark = (°C - 121) x 9/125, or Gas mark = (°C - 121) x 0.072

For example, what gas mark is 180 °C?

(180°C - 121) x 0.072 = 4,248, or simply 4.

Note: the equations only work for gas mark settings as one or higher. For gas marks below 1, it moves down to ½ instead of 0 and ¼ instead of -1.

How to convert Fahrenheit to Gas Mark

Gas mark = (°F - 250) x 1/25, or Gas mark = (°F - 250) x 0.04

For example, what is 300°F in the gas mark?

(300°F - 250) x 0.04 = 2.

How to convert Gas Mark to Celsius

°C = (Gas Mark x 125/9) + 121, or °C = (Gas Mark x 13.88) + 121

For example, how do you convert the gas mark 3 to Celsius?

(3 x 13.88) + 121 = 162.64, or to round it down, 160°C.

How to convert Gas Mark to Fahrenheit

°F = (Gas mark x 25) + 250

For example, what is gas mark 3 in Fahrenheit?

(3 x 25) +250 =325°F

Conclusion

Nothing is complicated about converting the oven temperature from one unit to another: Celsius to Fahrenheit to gas mark, and vice versa.

This article converts the different temperatures between Fahrenheit, Celsius, and gas marks.

It also provides a fan oven temperature conversion table and guidelines for adapting recipes that call for a regular oven to use a convection one.
