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.
  • Between neighbouring volume units it is easy to drop a power of ten: 1 cubic meter is 1,000 liters and 1 hectoliter is 100 liters. A 50 m³ pool holds 50,000 liters. Convert everything to liters before comparing and the slips become obvious.
