Formula & How Volume & Liquid Converter Works
Volume conversions depend on which gallon you mean. A US gallon is 3.78541 L, while an imperial gallon, used in the UK and historically in Australia, is 4.54609 L. So 50 L is 13.2 US gallons or 11.0 imperial gallons. One litre equals 1,000 mL and 1,000 cm³, and one cubic metre is 1,000 L. A US fluid ounce is 29.57 mL and an imperial fluid ounce is 28.41 mL. Cooking cups also differ: an Australian metric cup is 250 mL while a US cup is about 237 mL. Always check which unit system a recipe, fuel figure or specification is using before you convert.
