How to Convert Miles per gallon (US) to Liter per 100 kilometers

Converting Miles per gallon (US) (mpg (US)) to Liter per 100 kilometers (L/100km) is a core calculation in Fuel Economy, which measures the vehicular travel distance achieved per unit volume of consumed liquid or gaseous fuel. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Miles per gallon (US) equals 235.214583 Liter per 100 kilometers, while 1 L/100km equals 235.214583 mpg (US).

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (kilometer per liter (km/L)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 mpg (US) = 2.352146 kilometer per liter (km/L)
2. Target SI Bridge (ktarget):1 L/100km = 0.01 kilometer per liter (km/L)
Step-by-step substitution for Miles per gallon (US) → Liter per 100 kilometers:V(L/100km) = V(mpg (US)) × ( 2.352146 / 0.01 ) = V(mpg (US)) × 235.214583
Mathematical FormulaValue in Liter per 100 kilometers = Value in Miles per gallon (US) × 235.21458333Direct computational formula applied for standard conversion.
Worked Example

Converting 250 mpg (US) yields an exact output of 0.940858 L/100km in Liter per 100 kilometers. Under higher industrial throughput, 5000 mpg (US) translates to 0.0470429 L/100km.

Inverse check: 1 L/100km = 235.214583 mpg (US).
