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

Converting Gallon (US)/100 miles (gal (US)/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 (US)/100 miles equals 2.352146 Liter/100 km, while 1 L/100km equals 0.425144 gal (US)/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 (US)/100mi = 2.352146 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 (US)/100 miles → Liter/100 km:V(L/100km) = V(gal (US)/100mi) × ( 2.352146 / 1 ) = V(gal (US)/100mi) × 2.352146
Mathematical FormulaValue in Liter/100 km = Value in Gallon (US)/100 miles × 2.35214587Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 75 gal (US)/100mi, applying the conversion factor yields exactly 176.410941 L/100km. At larger operational scale, 1000 Gallon (US)/100 miles corresponds to 2352.145874 L/100km.

Inverse check: 1 L/100km = 0.425144 gal (US)/100mi.
