Oven Temperature Converter
Enter a Fahrenheit oven temperature to get the Celsius equivalent and the closest UK gas mark, using the standard published conversion table.
Gas mark is matched to the closest standard value, not computed from a formula, since the real published gas mark table isn't perfectly linear. If your recipe gives a gas mark and your oven only shows Celsius or Fahrenheit, use the exact standard value from the table rather than assuming a straight-line conversion.
Frequently asked questions
Why does this use a lookup table instead of a formula for gas mark?+
The real, standard gas mark table isn't perfectly linear with Fahrenheit or Celsius, it has small irregularities, especially at the low end. Matching against the actual published table is more accurate than a computed approximation would be.
My recipe gives Celsius, but my oven only shows gas mark, what do I do?+
Convert Celsius to the closest Fahrenheit value first (or use the Unit Converter's temperature mode), then match against the gas mark table here, rather than guessing at a straight-line relationship.
Are 'slow', 'moderate', and 'hot' oven descriptions standardized?+
Only loosely, they're common descriptive terms from older recipes (especially UK ones) rather than a strict standard, which is exactly why modern recipes specify an actual temperature instead of relying on them alone.
