About Oven Temperature Conversion
Converts a recipe temperature between oven types and then corrects for your own oven's measured error. Everything is normalised to a conventional-oven equivalent first, adjusted by 20 C for fan, and finally offset by the calibration error you measured with an oven thermometer.
Formulas
Fan conversion
A fan oven runs about 20 C hotter than a conventional oven at the same dial setting
Dial setting
Dial = required temperature - measured calibration error

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to whole numbers, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How do I measure my oven's calibration error?
Put an oven thermometer in the centre, set the dial to 180 C, and let it cycle for twenty minutes. The difference between reading and dial is the offset - negative if the oven runs cool.
Why does the offset get subtracted?
If the oven runs 8 C cool, you must set the dial 8 C higher to reach the real target. Subtracting a negative offset does exactly that.
