How it's calculated
Volume units convert exactly: every unit is a fixed number of millilitres (a US cup is 236.588, a tablespoon 14.787), so the amount times the “from” unit divided by the “to” unit is the answer. Weight works the same way in grams. Cups to grams is different because it depends on what is in the cup: a cup of flour weighs about 125 g and a cup of sugar 200 g. The ingredient list carries those densities per US cup, and the measure you used scales it. Recipes written by weight avoid the whole problem, which is why bakers love scales.
How many tablespoons in a cup?
16 US tablespoons, 48 teaspoons, 8 fluid ounces, 236.6 ml. A metric cup is 250 ml, a UK cup rarely used; the UK tablespoon is 15 ml and the Australian one 20 ml, which is where many recipe conversions go wrong.
Why do flour and sugar weigh different amounts per cup?
Density. Flour is light and full of air, about 125 g a cup spooned in or 150 g scooped and packed; sugar's crystals pack tightly to about 200 g. That 20% spread for flour alone is why baking recipes work better in grams.
Is a fluid ounce the same as an ounce?
No. A fluid ounce is volume (29.57 ml); an ounce is weight (28.35 g). They match for water and near enough for milk, but a fluid ounce of flour weighs about half an ounce and a fluid ounce of honey about 1.4 ounces. Use the Weight converter for ounces on a scale and the Volume converter for fluid ounces in a jug.
