How to Convert Liter/100 km to Gallon (US)/100 miles

Converting Liter/100 km (L/100km) to Gallon (US)/100 miles (gal (US)/100mi) is a core calculation in Fuel Consumption, which measures vehicular energy efficiency by comparing fuel volume burned per standard distance traveled. 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 Liter/100 km equals 0.425144 Gallon (US)/100 miles, while 1 gal (US)/100mi equals 2.352146 L/100km.

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 (liter per 100 kilometers (L/100km)) 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 L/100km = 1 liter per 100 kilometers (L/100km)
2. Target SI Bridge (ktarget):1 gal (US)/100mi = 2.352146 liter per 100 kilometers (L/100km)
Step-by-step substitution for Liter/100 km → Gallon (US)/100 miles:V(gal (US)/100mi) = V(L/100km) × ( 1 / 2.352146 ) = V(L/100km) × 0.425144
Mathematical FormulaValue in Gallon (US)/100 miles = Value in Liter/100 km × 0.4251437Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 250 L/100km, applying the conversion factor yields exactly 106.285925 gal (US)/100mi. At larger operational scale, 240 Liter/100 km corresponds to 102.034488 gal (US)/100mi.

Inverse check: 1 gal (US)/100mi = 2.352146 L/100km.
