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

Converting Gallon (UK)/100 miles (gal (UK)/100mi) to Liter/100 km (L/100km) 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 Gallon (UK)/100 miles equals 2.824811 Liter/100 km, while 1 L/100km equals 0.354006 gal (UK)/100mi.

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 gal (UK)/100mi = 2.824811 liter per 100 kilometers (L/100km)
2. Target SI Bridge (ktarget):1 L/100km = 1 liter per 100 kilometers (L/100km)
Step-by-step substitution for Gallon (UK)/100 miles → Liter/100 km:V(L/100km) = V(gal (UK)/100mi) × ( 2.824811 / 1 ) = V(gal (UK)/100mi) × 2.824811
Mathematical FormulaValue in Liter/100 km = Value in Gallon (UK)/100 miles × 2.82481088Direct computational formula applied for standard conversion.
Worked Example

Converting 250 gal (UK)/100mi yields an exact output of 706.20272 L/100km in Liter/100 km. Under higher industrial throughput, 2500 gal (UK)/100mi translates to 7062.027197 L/100km.

Inverse check: 1 L/100km = 0.354006 gal (UK)/100mi.
