Oven Temperature Conversions.

Found a recipe you want to try but it only gives oven temperature Fahrenheit and you cook with gas?

What is meant by "cook in a moderate oven"?

Your new cooker has Celsius markings, how do you convert your old recipes that are in Fahrenheit?

All very good questions that this page will, I hope, answer.

There is another set of descriptive references to the heat level that I have come across that may be found on older recipes. In fact it is so old it only equated to Fahrenheit with no mention of gas or Centigrade at all

I have included it here for reference just in case you need it.

Bear in mind that these are a guide only and not exact conversions. As a rule of thumb Celsius is approximately half the Fahrenheit temperature.

Fan assisted ovens are usually set approximately 25 degrees Celsius (approximately 50 degrees Fahrenheit) lower than non fan assisted and cooking time is reduced by 10 minutes for every hour of cooking time.

Different manufacturers and oven types do vary, so always refer to your cooker instruction book if you have it.

Also take note of position, if noted in the recipe. Some recipes require the use of the top of the oven (hottest part) and others my say centre or bottom (progressively cooler), although this tends not apply to fan assisted ovens as they distribute their heat evenly throughout the oven.
