Conversion tables
All these are approximate conversions, which have either been rounded up or down. In a few recipes, it has been necessary to modify them very slightly. Never mix metric and imperial measures in one recipe; stick to one system or the other.

If using a fan oven you will need to reduce the oven temperature in a recipe by 20 degrees.

Note: A pint isn't always a pint: in British, Australian and often Canadian recipes you'll see an imperial pint listed as 20 fluid ounces. American and some Canadian recipes use the the American pint measurement, which is 16 fluid ounces.
