Mistakes to avoid with volume conversions
- US vs imperial gallons: the imperial gallon is ~20% larger — UK fuel-economy figures aren't US ones.
- Converting milliliters to grams for ingredients that aren't water — oil, flour and honey have different densities.
- US recipe cups (236.6 ml) vs metric cups (250 ml) — a 5% error that ruins delicate baking.
