Common volume conversion mistakes

  • 'Gallon' names two different measures: the US gallon is about 3.785 liters and the imperial gallon about 4.546 liters, a full 20% larger. US fuel figures and UK recipes therefore use different gallons. Always check the country before converting.
  • A fluid ounce measures volume, not weight. The US fl oz is about 29.57 ml and the imperial fl oz about 28.41 ml, and neither matches the weight ounce (28.35 g) except roughly for water. Measure liquids in milliliters to avoid the ambiguity.
