Fuel Efficiency (Mass) Converter
Fuel efficiency by mass expresses the distance travelled per unit mass of fuel rather than per unit volume. Measuring fuel by mass avoids the errors caused by temperature changing a liquid’s volume, and suits fuels that are sold by weight.
1 Kilometer/Kilogram = 0.2818492317 Mile/Pound
How to convert Kilometer/Kilogram to Mile/Pound
One Kilometer/Kilogram equals 0.2818492317 Mile/Pound, so multiply any value in km/kg by 0.2818492317 to get mi/lb. To convert back, divide by 0.2818492317 — or multiply by 3.547996189.
mi/lb = km/kg × 0.2818492317
Example: 25 km/kg × 0.2818492317 = 7.046230793 mi/lb.
