Tips & common mistakes

Quick tips

  • 1 L = 1000 ml = 1 dm³ = 0.001 m³ exactly.
  • 1 L of water weighs 1 kg at 4 °C — use for quick mass estimates.
  • Fuel economy in Europe is litres per 100 km; lower is better. US uses mpg where higher is better.

Avoid these

  • Confusing L (litre) with l (lowercase), since lowercase l can be mistaken for digit 1. Capital L is preferred.
  • Mixing litres and US gallons in fuel economy discussions.
  • Writing engine displacement in ml instead of L — 1500 cc = 1.5 L.
