30 MPG (US)
Approximately 7.840486 L/100 km, 12.754311 km/L, and 36.028498 MPG (Imperial).
Convert fuel economy and consumption among US MPG, Imperial MPG, kilometers per liter, and liters per 100 kilometers.
Fuel economy describes distance traveled per amount of fuel. MPG and km/L are distance-per-fuel measurements, so larger numbers represent more distance from the same fuel quantity.
Fuel consumption describes fuel used per distance. L/100 km runs in the opposite direction: a smaller number represents less fuel used over 100 kilometers.
L/100 km = (3.785411784 × 100 ÷ 1.609344) ÷ MPG (US)L/100 km = (4.54609 × 100 ÷ 1.609344) ÷ MPG (Imperial)L/100 km = 100 ÷ (km/L)km/L = 100 ÷ (L/100 km)Approximately 7.840486 L/100 km, 12.754311 km/L, and 36.028498 MPG (Imperial).
Approximately 29.401823 MPG (US) and exactly 12.5 km/L.
Exactly 5 L/100 km and approximately 47.042917 MPG (US).
Miles traveled per US gallon, using exactly 3.785411784 liters per gallon.
Miles traveled per Imperial gallon, using exactly 4.54609 liters per gallon.
Kilometers traveled for each liter of fuel.
Liters consumed over 100 kilometers. Lower values indicate less fuel consumption for the same distance.
US and Imperial MPG are different because an Imperial gallon is larger than a US gallon. The same vehicle therefore has a numerically higher MPG value when expressed with Imperial gallons.
MPG and km/L put distance above fuel, while L/100 km puts fuel above distance. Converting between them requires a reciprocal rather than only multiplying by a fixed factor.
At zero, that reciprocal has no finite numeric result. The calculator reports the mathematical boundary in words instead of displaying Infinity.
Divide the appropriate gallon-specific conversion constant by MPG. US and Imperial gallons require different constants.
Divide the appropriate gallon-specific conversion constant by the L/100 km value.
They use different gallon sizes: 3.785411784 liters for a US gallon and 4.54609 liters for an Imperial gallon.
A higher MPG value generally means more distance per unit of fuel, but this calculator does not rate individual values as good or bad.
A lower L/100 km value generally means less fuel used for the same distance.
Approximately 12.754311 km/L.
It measures fuel per distance, while MPG and km/L measure distance per fuel.
It represents zero fuel consumption and corresponds to an unbounded distance-per-fuel value, so no finite MPG result exists.
Negative fuel economy is not meaningful for ordinary vehicle consumption, so negative input is rejected.
Exactly 3.785411784 liters for the US gallon and 4.54609 liters for the Imperial gallon.
