Just about every food website in the world, along with the majority of recipe or culinary training books have an oven temperature conversion table.
Well, here is another one. Not just because I so love typing out tables of data, but also because this site contains a number of recipes and it seems only right to provide all of the info that you need to cook them in the same place.
I’ve added a separate column for fan assisted ovens in °C, the general rule is that you subtract 20°C (about 36°F) when using a fan oven.
| °C | °F | |
| Water freezes | 0 | 32 |
| Water boils | 100 | 212 |
Oven Temperatures
| °C | °C (fan) | °F | Gas Mark | |
| Very cool | 110 | 90 | 225 | ¼ |
| 130 | 110 | 250 | ½ | |
| Cool | 140 | 120 | 275 | 1 |
| 150 | 130 | 300 | 2 | |
| Moderate | 170 | 150 | 325 | 3 |
| 180 | 160 | 350 | 4 | |
| Moderately hot | 190 | 170 | 375 | 5 |
| 200 | 180 | 400 | 6 | |
| Hot | 220 | 200 | 425 | 7 |
| 230 | 210 | 450 | 8 | |
| Very hot | 240 | 220 | 475 | 9 |
If you want to convert between any temps that aren’t listed here, don’t forget that you can always use Google for just about type of conversion, simply by typing the amount you want to convert and the from and to units into the search bar.

Thank you! I wondered why everything was overcooked or burned in my new fan oven even though I followed the recipes.

Glad it helped!
Every fan oven is slightly different, so you will need to experiment slightly, but the rule above is pretty reliable.

this is so helpful thank you so much

At last! I now have a proper conversion of gas regulos for my fan oven. I’ve been struggling for so long to get the correct temperature for my food. Many thanks judith

Glad that it helped Judith – It seems that the majority of temp conversion charts don’t bother to mention the fact that fan ovens need to be much lower than conventional ovens.

Thanks for the temeratures. I have just purchased a new fan assisted/’normal’ oven. Do I also have to adjust the cooking time please, or do I just follow the instuctions, but knock the temperature down?
August 10th, 2010 at 2:22 pm
Hi Paula,
The easiest thing is just to leave the cooking time as it in the recipe, and adjust the temperature downwards.

Thank you so much for sharing this information with us. I had been used to a simple gas oven, then moved into a house with a fan-forced electric oven. There was no instruction manual available to teach me the intricacies of this, though! After several burnt offerings, I decided to search the web and was very grateful to come across this site.

Hi! thanks for the NEW chart, i had an OLD chart from a circafan oven from 17YRS ago and wondered why nothing cooked correctly! the oven was a fan but its chart is completely different in conversion to yours i would say it was out about 20percent, my fan chart said gas 5 was 150c yours says 170c, i wondered why everything took longer in my new one. thanks again sheila

Thank you so very much. I looked into every cook book I have and found nothing. You have answered my father’s dream of my baking lots of cakes for him so he thanks you too! xxx

thank you mum found it difficult converting tempratures,as an avid baker this information is invaluable as she couldnt get any information in all her cookery books so big thank you to your sight.xxx

I am glad that you are all finding the chart useful.
It is such a simple thing, but if you don’t have the information it makes baking or roasting anything a complete guessing game.
If you are converting recipes from different countries, here is another chart that you might also find useful: http://johnonfood.com/ingredients/egg-sizes/

Hi I have always cooked by gas but moved to a new apartment and it has fan assisted electric. I would like to know how i can convert temperatures from gas to electric Thank You
March 16th, 2011 at 11:01 am
Hi Rose,
Just use the table above, the last column is the gas mark that you would normally use.
Find the gas mark and then just follow the row across and set your electric oven to that temperature.

I’ve just got a fan assisted oven and cooked a brisket of be with vegetables. Unfortunatley the veg didn’t cook through can you explain why this has happened?

Hi,
I’ve just moved and there is a fan oven in the house. It’s Hygena turbo Model AHY3220.
I don’t understand the temp markings. They go up in 10s…starting at 0 and up tp 50.
Can you give me some help please?
Thanks in anticipation.

I can’t find a comparison for gas oven settings between natural gas and LPG. Can anyone help please?
October 7th, 2011 at 2:37 pm
Thankyou this helps alot. I have been used to gas for many years.

Im using an old Mary Berry book for her traditional christmas recipe. The first two turned out ok with me adjusting the fan oven temp to what I thought, but were a bit dry. I read somewhere that you should reduce the temp by 25% to get the correct temp for a fan oven. However, I wanted to get it absolutely correct and, having found this conversion table, it seems to confirm that the 25% less rule is about right. Thanks for making this easier for me. Many thanks.

I have recently moved house and don’t know how to convert gas mark to electric – I used to use a gas cooker but in my new house there is an electric one. The table above doesn’t help because the temperature dial goes up in ones, so 1 2 3 4 5 etc… I don’t think it is gas mark. The recipe I am using is for a tart base and I need to convert gas mark 7 to electric. Can anyone help?
October 26th, 2011 at 2:02 pm
@ Lola – I have no idea how that works, maybe the best thing would be to use an oven thermometer to work out what the numbers on your dial mean. You can pick them up pretty cheaply from any kitchen shop.
October 29th, 2011 at 10:18 pm
Hi I have exactly the same problem as Lola, my electric oven dial is numbered 1 to 10, surely there is a guide for electric ovens that simply states what temperature each number represents WITHOUT giving GAS conversion charts, please help
November 10th, 2011 at 11:28 am
@ Lola and Anne – I wish I could help you, but I have never seen an oven marked like that, I would guess that the numbers are equivalent to gas marks, but if not then I have no idea. Sorry

We have recently had a new cooker the fan assisted oven has a rear fan but a top and bottom element I am experimenting at the moment the recommendation is bottom heat with fan for sponge cakes 180c but they burn at the bottom I am on my third cake mix any suggestions I am currently experimenting with each configuration top element Bot element both elements etc help!
November 23rd, 2011 at 11:00 am
We have a new electric cooker which has the option of with or without fan. Without fan (conventional) set on, say 180, a portable oven thermometer in the middle of the oven reads 180. If the oven is now set to 160 with fan, (the equivalent) the portable thermometer still reads 180. Why is this?

I have A Necht Electric Convection Oven and I have lost the instruction book can you please advise where I could get one or download one? Thanks

Dear John, I have a fan assisted gas oven, if my recipe says cook on gas mark 5, do I need to reduce the temperature to gas mark 4 or 3.
Thanks Eileen
December 17th, 2011 at 12:29 am
I am bookmarking this asap! Thank you very much
December 23rd, 2011 at 1:04 pm
Just found this great site and was about to ask exactly the same as Eileen; if recipe says Gas Mk8 I reckon between 6 and 7 to allow for the fan?
January 11th, 2012 at 6:22 pm
This site is fantastic! After a few disasters, last being apple crumble exploding all over the oven, I decided to check temps for fan ovens. I have never cooked with a fan oven before and this info is invaluable. Thank you very much John. Joy

I have found this information very helpful but still can’t for the life of me understand why supermarkets don’t just print the extra temperatures for fan assisted ovens on the cooking instructions. Surely this would be easier as most ovens (intergral or freestanding) nowadays come fan assisted. The oven I have recently bought has a double oven with the lower being fan assisted and the smaller upper one being conventional type.
