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

Converting Miles per gallon (UK) (mpg (UK)) 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 (UK) equals 282.480936 Liter per 100 kilometers, while 1 L/100km equals 282.480936 mpg (UK).

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 (UK) = 2.824809 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 (UK) → Liter per 100 kilometers:V(L/100km) = V(mpg (UK)) × ( 2.824809 / 0.01 ) = V(mpg (UK)) × 282.480936
Mathematical FormulaValue in Liter per 100 kilometers = Value in Miles per gallon (UK) × 282.48093633Direct computational formula applied for standard conversion.
Worked Example

To convert 2.5 Miles per gallon (UK) (mpg (UK)) to Liter per 100 kilometers (L/100km): multiply 2.5 by 282.480936 to get 112.992375 L/100km. At an industrial engineering scale, 1000 mpg (UK) converts to 0.282481 L/100km.

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