UNIT : Unit : Volume 12 : Fuel Consumption - Volume per Length : Unit Conversion Tool

Description : Convert between fuel economy or volume per distance units.

Standard Unit : STD unit liter per kilometer [l/km].

Discussion : The tool can convert directly between volume per distance units and distance per volume units (fuel economy units). Imperial units are based on the US statute foot = 0.3048 meters.

Units :

• uk gallon per mile [ gal-uk/mi ]
• us gallon per mile [ gal-us/mi ]
• kilometer per liter [ km/l ]
• liter per 100 kilometer [ l/100.km ]
• [STD] liter per kilometer [ l/km ]
• liter per meter [ l/m ]
• cubic meter per kilometer [ m³/km ]
• mile per uk gallon [ mi/gal-uk ]
• mile per us gallon [ mi/gal-us ]
