About the units
Volume units explained
Volume is where the US and UK differ most. A US gallon is about 3.785 liters, an imperial gallon about 4.546 liters. Pints and fluid ounces differ too, so check which system a recipe or label uses.
Kitchen measures add their own twist: a US cup is 236.6 ml, while many metric recipes use a 250 ml cup. For baking, weighing ingredients is more reliable than measuring them by volume.
