About Volume Units
Volume measures three-dimensional space. The SI unit is the litre (L), defined as 1 dm³ (one cubic decimetre). A US gallon (3.785 L) differs from a UK/Imperial gallon (4.546 L) — important when comparing fuel prices or recipes. Cooking uses cups, tablespoons, and teaspoons, which also differ slightly between US and metric standards.
