Oven temperatures

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.

Oven settings Fahrenheit Celsius
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)
