Conversion tables

The values in these conversion tables are only approximate and have been rounded up or down for clarity. Always stick to either metric or imperial measurements in the same recipe.

100's of our ingredients pages now have (US) cup to weight conversion tables to, so if you need to know how much a cup of parsley weighs, just enter Parsley in the search box and click Go. The cup-to-weight calculations are at the bottom of every ingredient page.

Oven Temperatures

Oven temperatures can be in degrees Celsius (International) -- previously Centigrade, degrees Fahrenheit (in the USA) or by gas mark (UK). This table provides a rough guide to conversion between the ranges.

For fan assisted ovens, use a setting of 20° Celsius (68° Fahrenheit) less than the recipe calls for. Cooking times can probably be reduced by 10 minutes for every hour of cooking time.

The fan oven temperatures are the equivalent to all of the left hand values.

Centigrade	Farenheit	Gas Mark	Descriptive	=	Fan Oven equiv. °C
110°	225°	¼	Very slow/Very low	=	90°
120°	250°	½	Very slow/Very low	=	100°

190°	375°	5	Moderate/Moderately hot	=	170°
200°	400°	6	Moderately hot	=	180°
220°	425°	7	Hot	=	200°
230°	450°	8	Hot/Very hot	=	210°
250°	475°	9	Very hot	=	230°

Note on cup measurements.

In 'modern' recipes, use of the cup measure appears mainly in American recipes. Even here in the UK, there are 2 standards. The Commonwealth or Imperial cup measurement is 1/2 pint though in practice it is only commonly used in historic/old recipes. If your recipe uses cups as the 'base' measurement for all ingredients, then you should be OK. If you are uncertain, err on the side of caution (play it safe). In general, it is easy to add a little more of an ingredient - it is much harder (impossible??) to take it away again after adding it. Wikipedia article on cup measures
