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

Converting Liter per 100 kilometers (L/100km) to Miles per gallon (UK) (mpg (UK)) 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 282.480936 Miles per gallon (UK), while 1 mpg (UK) equals 282.480936 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 mpg (UK) = 2.824809 kilometer per liter (km/L)
Step-by-step substitution for Liter per 100 kilometers → Miles per gallon (UK):V(mpg (UK)) = V(L/100km) × ( 0.01 / 2.824809 ) = V(L/100km) × 282.480936
Mathematical FormulaValue in Miles per gallon (UK) = Value in Liter per 100 kilometers × 282.48093633Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 12 Liter per 100 kilometers (L/100km) produces 23.540078 Miles per gallon (UK) (mpg (UK)). In heavy-duty utility and industrial workloads, 480 L/100km equals 0.588502 mpg (UK).

Inverse check: 1 mpg (UK) = 282.480936 L/100km.
