How many milliliters are in a cup?

A US recipe cup is 236.59 mL, though the US legal cup used on nutrition labels is 240 mL. A metric cup, used in Australia and much of the UK, is 250 mL. Because they differ, weighing ingredients in grams is more reliable than measuring by cup.

How many tablespoons are in a cup?

16 US tablespoons in 1 US cup, and 3 teaspoons in 1 tablespoon. That makes 1 cup equal to 48 teaspoons. Australian tablespoons are 20 mL rather than 14.79 mL, so Australian recipes asking for a tablespoon want noticeably more.

What is gas mark 4 in Celsius?

Gas mark 4 is 180 °C, or 350 °F — the temperature most baking recipes call for. The full mapping is in the oven chart above, covering gas marks 1 to 9.

Do I need to adjust the temperature for a fan oven?

Usually yes: reduce by about 20 °C (or 25–50 °F) compared with a conventional oven, because circulating air transfers heat more efficiently. Many modern ovens do this automatically, so check the manual before adjusting.

Why do recipes say to weigh flour instead of using cups?

Because a cup of flour can weigh anywhere from 110 g to 150 g depending on how it is scooped and whether it is sifted. That variance is enough to change the texture of bread and cakes, which is why professional recipes give weights.
