Frequently Asked Questions
How do I convert L/100km to MPG?
To convert L/100km to US MPG, divide 235.215 by L/100km. For example, 8 L/100km = 235.215 ÷ 8 = 29.4 MPG US. For UK MPG, divide 282.481 by L/100km. Note: lower L/100km is better, while higher MPG is better.
Why are L/100km and MPG inversely related?
L/100km measures fuel consumed per distance (more is worse), while MPG measures distance per fuel (more is better). They're mathematical inverses: if L/100km doubles, MPG halves. That's why you divide rather than multiply when converting.
What's the difference between US MPG and UK MPG?
US gallon = 3.785 liters, while UK (imperial) gallon = 4.546 liters (20% larger). Therefore, 30 MPG US = 36 MPG UK for the same efficiency. Always check which MPG rating you're comparing when looking at fuel economy.
How do I convert MPG to km/L?
To convert US MPG to km/L, multiply by 0.425144. For example, 30 MPG US = 30 × 0.425144 = 12.75 km/L. For UK MPG to km/L, multiply by 0.354006. km/L is commonly used in Asia and some other regions.
What's good fuel economy in different units?
Good economy varies by vehicle type: Compact car: 6-7 L/100km (35-40 MPG US, 40-50 MPG UK). SUV: 8-10 L/100km (23-29 MPG US, 28-35 MPG UK). Remember: lower L/100km = higher MPG = better efficiency.
