Conversion table
| From | To |
|---|
One hundred to two hundred and fifty Celsius in ten-degree steps, which is the range an oven dial covers and the interval it is marked in. A chart in single degrees would be precision an oven does not have.
An oven is not an accurate instrument. A domestic one commonly runs ten to twenty degrees Celsius away from its dial, and drifts as it cycles, so the conversion below is the smaller of the two errors between you and the right temperature. An oven thermometer costs very little and is the only way to know.
Fan ovens are the other trap. A recipe written for a conventional oven wants about twenty degrees Celsius less in a fan oven, because moving air carries heat to the food faster than still air does. That adjustment is not a unit conversion and is not in the table: apply it to the Celsius figure first, then read across.
For weather rather than baking, the Celsius to Fahrenheit chart covers minus ten to forty in single degrees.
How to use it
- Read the table, which is built for this pair of units when the page opens.
- Change Start, Step or Rows to cover a different range.
- Press Print for the table on its own, without the rest of the page.
Questions
What is 180C in Fahrenheit?
356F, which nearly every recipe rounds to 350F. The rounding is harmless because the difference is well inside what a domestic oven can hold: most run ten to twenty degrees Celsius off their dial in one direction or the other.
Do I reduce the temperature for a fan oven?
Yes, by about twenty degrees Celsius, or thirty-five Fahrenheit, from what a conventional recipe states. Fan ovens move air across the food, which transfers heat faster than still air. Make that adjustment to the Celsius figure before reading the table, since it is a cooking correction rather than a unit conversion.
What are gas marks in Celsius?
Gas mark 4 is 180C, and each mark up or down is roughly fourteen degrees Celsius: mark 1 is 140C, mark 6 is 200C, mark 9 is 240C. The scale is not on this chart because it is a British oven marking rather than a unit, and it does not convert by multiplication.
Can I change the range of the chart?
Yes. Start is the first value in the left column, Step is the gap between rows, and Rows is how many there are, up to two hundred. All three update the table as you type, and the unit menus above them will convert any other pair in the same category.
Is the table built on my device?
Yes, by WebAssembly compiled from Rust, using conversion factors that are compiled in rather than fetched. Nothing is uploaded, nothing is stored, and the page prints the same table with the network off.
