12.7543 Km/L
How This Works
MPG measures distance per unit of fuel (higher is better), while L/100km measures fuel per unit of distance (lower is better) — they're inversely related, so doubling your MPG doesn't halve your L/100km in a simple linear way. Km/L is directly proportional to MPG instead, just in different units.
Formula
L/100km = 235.215 ÷ MPG
Km/L = MPG × 0.425144
Examples
20 MPG ≈ 11.76 L/100km
30 MPG ≈ 7.84 L/100km
40 MPG ≈ 5.88 L/100km
50 MPG ≈ 4.70 L/100km
Frequently Asked Questions
What is 30 MPG in Km/L?
30 MPG equals 12.7543 Km/L.
Why isn't the MPG to L/100km relationship linear?
Because MPG measures distance per fuel unit while L/100km measures fuel per distance unit — they're reciprocals of each other, not proportional.
