Conventional oven conversion chart

Conventional 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 cheat sheets to help convert your recipes into the temperature units of your preference.

They are created for temperatures of conventional ovens (aka traditional ovens).

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.

Verbal to Fahrenheit, Celsius, and Gas Mark

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

Verbal	Fahrenheit	Celsius	Gas mark
Cool/Very Slow Cook	250°F	121°C	½
Warm/Slow Cook	300°F	148°C	2
Moderate	350°F	176°C	4
Moderately hot	375°F	190°C	5
Hot	425°F	218°C	7
Very hot	450°F	232°C	8
Extremely hot	475°F	246°C	9

Convection oven conversion chart

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 be gas, 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 cut the cooking time by 25 percent.

If you use a fan-assisted gas oven, reduce the gas mark by 1.

And if you use an electric fan oven, you should reduce the temperature by 20°C.

But 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.

And 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.

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

Conventional oven	Convection oven
225°F	200°F
250°F	225°F
275°F	250°F
300°F	275°F
325°F	300°F
350°F	325°F
375°F	350°F
400°F	375°F
425°F	400°F
450°F	425°F
475°F	450°F
500°F	475°F

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).

Oven conversion formulas

Here is a question: how to convert the oven temperature not included in the above charts?

There is no problem since there are all the equations to convert between Fahrenheit, Celsius, and gas mark.

The equation to convert from Celsius to Fahrenheit

°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.

The equation to convert from Fahrenheit to Celsius

°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.

The equation to convert from Celsius to gas mark

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 for 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.

The equation to convert from 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.

The equation to convert from gas mark to Celsius

°C = (Gas Mark x 125/9) + 121, or

°C = (Gas Mark x 13.88) + 121

For example, how to convert gas mark 3 to Celsius?

(3 x 13.88) + 121 = 162.64, or

to round it down, 160°C.

The equation to convert from 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
