How to Convert Liter per 100 kilometers to Gallon (UK) per 100 miles

Converting Liter per 100 kilometers (L/100km) to Gallon (UK) per 100 miles (gal (UK)/100mi) 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 Liter per 100 kilometers equals 0.354006 Gallon (UK) per 100 miles, while 1 gal (UK)/100mi equals 2.824809 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 (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 L/100km = 0.01 kilometer per liter (km/L)
2. Target SI Bridge (ktarget):1 gal (UK)/100mi = 0.0282481 kilometer per liter (km/L)
Step-by-step substitution for Liter per 100 kilometers → Gallon (UK) per 100 miles:V(gal (UK)/100mi) = V(L/100km) × ( 0.01 / 0.0282481 ) = V(L/100km) × 0.354006
Mathematical FormulaValue in Gallon (UK) per 100 miles = Value in Liter per 100 kilometers × 0.35400619Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 2.5 Liter per 100 kilometers (L/100km) produces 0.885015 Gallon (UK) per 100 miles (gal (UK)/100mi). In heavy-duty utility and industrial workloads, 2500 L/100km equals 885.015475 gal (UK)/100mi.

Inverse check: 1 gal (UK)/100mi = 2.824809 L/100km.
