About this converter
US vs. UK gallons
These are different. 1 US gallon = 3.785 L, but 1 UK Imperial gallon = 4.546 L (about 20% bigger). UK fluid ounces are also slightly different from US.
Cooking conversions
1 US cup = 16 tbsp = 48 tsp = 8 fl oz = ~237 mL. UK and Australian recipes sometimes use slightly different cup sizes (250 mL is common in Australia).
Liquid vs. dry
This converter handles liquid (fluid) volumes. Dry measures (e.g., dry pints for produce) exist in the US system but are rare; use this for almost all everyday conversions.
