Oven settings can be confusing between different scales. Find below the guidelines for the right oven temperatures.
This chart is only a guide. The last column shows the nearest temperature equivalent to the gas numbers, but most ovens give temperatures in units of 25˚ F, 10˚ C or 20˚ C to make the setting easier. The first scale of settings - slow, moderate, hot - are the terms we used in the USA; the second one - cool, moderate, hot - are the popular terms we used in the UK. In most European countries, we used a mixture of both - very cool, cool, moderate, hot, very hot - but the temperature intervals are approximately the same.
|very slow (very cool)||225˚ to 250˚||120˚ to 140˚|
|slow (cool)||275˚ to 300˚||140˚ to 160˚|
|moderate||325˚ to 350˚||160˚ to 180˚|
|hot (fairly hot)||375˚ to 400˚||180˚ to 200˚|
|very hot (hot)||425˚ to 450˚||200˚ to 220˚|
|extremely hot (very hot)||475˚ to 500˚||250˚|
Oven temperatures given above are for conventional ovens.
Fan assisted ovens take less time to cook because of the hot air circulation and they usually need a lower temperature, a approximately 20% less (approximately 20° F to 40° F, or 10° C to 20° C, less)
