US vs UK Measurements
A common source of confusion is that US and UK fluid measurements differ. A US gallon is 3.785 liters while a UK imperial gallon is 4.546 liters — about 20% larger. Similarly, a US cup is 236 mL while a metric cup (used in Australia/Canada) is 250 mL. When following recipes, always confirm which standard is used.
