How to Convert Kilometer/Gallon (UK) to Liter/Kilometer

This conversion uses an offset formula, so it cannot be described by a single multiplication factor.

Formula: L/km = km/gal (UK) × 4.5460918869

Reverse: km/gal (UK) = L/km × 4.5460918869

Step-by-Step Example

Start with your value in Kilometer/Gallon (UK). For example: 5 km/gal (UK)
Apply L/km = km/gal (UK) × 4.5460918869
The result is: 0.909218 L/km
