Cups, grams, and why recipes fail across the Atlantic
A cup of flour can vary by 30% depending on who scooped it. The unit traps hiding in international recipes, and how to bake around them.

If you’ve ever followed a foreign recipe precisely and produced a brick, units probably sabotaged you. Cooking measurements hide three separate traps: volume versus weight, US versus imperial versus metric, and ingredients that refuse to be measured by volume at all.
The cup problem
A US cup is 236.6 mL. An old imperial cup is 284 mL. A metric cup, used in Australian recipes, is 250 mL. Same word, three sizes — an Australian recipe measured with American cups quietly shrinks every ingredient by 5%, and an old British one overshoots by 20%.
Worse, a ‘cup of flour’ isn’t even a fixed amount of flour. Scooped straight from the bag it packs down to 140+ grams; spooned in and leveled it’s closer to 120. That’s a 15-20% swing on the ingredient that defines your dough. Professional bakers weigh everything, and this is why.
Weight is the only honest measure
My advice after years of ruined Sunday bakes: buy a $15 kitchen scale and treat grams as the recipe’s real language. Weight doesn’t care how compacted the flour is or whose cup you own. European recipes are already written this way. When you get an American recipe in cups, convert the wet ingredients with our Volume category (cups to mL is exact) and look up standard weights for the dry ones — most serious recipe sites now list both.
The oven is lying too
Gas mark 4 is 350°F is 177°C — and your actual oven is probably 10-25 degrees off its dial in either direction. Temperature conversion between recipe traditions is one converter click, but for baking, an oven thermometer fixes the error the dial hides. Between a scale and a thermometer, you remove the two biggest reasons the same recipe behaves differently in two kitchens.
