## What about fan/convection ovens?

To keep the tables nice and simple, I’ve only provided temperatures for conventional ovens.

If you have an electric fan oven, you’ll need to reduce the Celsius temperature by 20℃.

If you are using a fan-assisted gas oven then reduce the gas mark by 1.

If you have a US convection oven then lower the temperature by 25℉.

## Need to convert from a temperature that’s not included in the tables?

That’s no problem! Here are all the equations you need to convert between Celsius, Fahrenheit and gas mark for any other values.

Before you start, there are a few things to note:

- It’s unlikely you’ll get a nice round number from the calculations, so you’ll need to round the result to the nearest degree.
- These equations only work for gas marks of 1 or more (because of how the gas mark system was designed). For gas marks below 1, it moves down to ½ and then a ¼ instead of 0 and -1.
- Any maths geeks out there may notice that I have simplified the equations between Gas Mark and Celsius ever so slightly, but they will still give you the correct result after rounding.

## The equation to convert from Celsius to Fahrenheit

℉ = (℃ x ^{9}⁄_{5}) + 32

## The equation to con vert from Celsius to Gas Mark

Gas Mark = (℃ – 121) x ^{9}⁄_{125}

## The equation to convert from Fahrenheit to Celsius

℃ = (℉ – 32) x ^{5}⁄_{9}

## The equation to convert from Fahrenheit to Gas Mark

Gas Mark = (℉ – 250) x ^{1}⁄_{25}

## The equation to convert from Gas Mark to Celsius

℃ = ((Gas Mark x ^{125}⁄_{9}) + 121)

## The equation to convert from Gas Mark to Fahrenheit

℉ = (Gas Mark x 25) + 250
