US gallon = 3.785L, UK gallon = 4.546L. Check your recipe's origin!
Cooking Conversions
1 cup = 240ml (US), 1 tbsp = 15ml. Professional bakers prefer weight.
Metric vs Imperial
Metric is base-10 (1000mL = 1L). Imperial: 8 fl oz = 1 cup, 4 qt = 1 gal.
Industrial Use
Oil uses barrels, construction uses cubic meters, water uses acre-feet.
Key conversions: 1 US gallon = 3.785 L, 1 UK gallon = 4.546 L (20% larger!). Cooking: 1 cup = 240 mL, 1 tbsp = 15 mL, 1 tsp = 5 mL. 1 liter = 0.001 m³.
