Kilometers per liter to Miles per gallon (US) Conversion Table
Common values, ready to copy:
| kilometers per liter | miles per gallon (US) |
|---|---|
| 1 km/L | 2.3521 mpg (US) |
| 2 km/L | 4.7043 mpg (US) |
| 5 km/L | 11.7607 mpg (US) |
| 10 km/L | 23.5215 mpg (US) |
| 25 km/L | 58.8036 mpg (US) |
| 50 km/L | 117.61 mpg (US) |
| 100 km/L | 235.21 mpg (US) |
| 1,000 km/L | 2352.15 mpg (US) |
Formula
mpg(US) = km/L × 2.3521
Fuel economy can be expressed as distance per unit fuel (mpg, km/L, higher is better) or fuel per unit distance (L/100km, lower is better). They convert via inverse: mpg(US) × L/100km = 235.2146.
About Kilometers per liter and Miles per gallon (US)
Kilometers per liter (km/L): Inverse of L/100km — distance traveled per fuel volume; less common than L/100km but used in some Asian markets. Common uses: Vehicle fuel economy in Japan, India, and several other Asian markets; conceptually similar to mpg but in metric units.
Miles per gallon (US) (mpg (US)): Distance per US gallon of fuel; the US standard for fuel economy. Common uses: US vehicle window stickers (EPA-rated mpg), US car reviews, and US fleet fuel economy.
How the conversion works
Fuel economy can be expressed as distance per unit fuel (mpg, km/L, higher is better) or fuel per unit distance (L/100km, lower is better). They convert via inverse: mpg(US) × L/100km = 235.2146.
The exact relationship is mpg(US) = km/L × 2.3521, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between kilometers per liter and miles per gallon (US) comes up wherever fuel economy measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
