Fuel Efficiency Converter
Convert between MPG, L/100km, and km/L
// L/100km vs MPG
L/100km measures fuel consumed per distance (lower is better). MPG measures distance per fuel unit (higher is better). They're inversely related: 8.5 L/100km ≈ 27.7 MPG (US).
// US vs Imperial
A US gallon is 3.785L. An Imperial gallon is 4.546L (20% larger). So Imperial MPG numbers are always higher than US MPG for the same car. Don't mix them up!
// SA Standard
South Africa uses L/100km. A typical sedan does 7-9 L/100km. A fuel-efficient hybrid does 4-5 L/100km. SUVs and bakkies often use 10-14 L/100km.
// Improve Efficiency
Maintain tyre pressure, drive at steady speeds, avoid harsh acceleration, remove unnecessary weight, and use cruise control on highways. These can improve efficiency by 10-20%.
