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.
  • The US recipe cup is about 237 ml, neither 250 ml nor 200 ml. Rounding up to 250 ml makes a batch about 6% too big; rounding down to 200 ml about 15% too small. Use 2.4 dl per cup, or the exact 236.6 ml when baking demands precision.
