Volume

1 US cup = 240ml. 1 UK cup = 284ml. 1 tablespoon = 15ml. 1 teaspoon = 5ml. 1 fl oz = 29.57ml. Australian tablespoon = 20ml (slightly larger than UK/US). Always specify which cup measurement a recipe uses.

Weight

1 oz = 28.35g. 1 lb = 453.6g. 1 stone = 6.35kg. For baking especially, weight is always more accurate than volume — flour in particular can vary by 20% or more between a scooped and sifted cup.

Oven Temperature

Gas mark 1 = 140°C = 275°F. Gas mark 4 = 180°C = 350°F (moderate). Gas mark 7 = 220°C = 425°F (hot). Gas mark 9 = 240°C = 475°F (very hot). Fan ovens typically run 15–20°C hotter than stated — reduce setting accordingly.
