    How to Convert Kilometer/Gallon (US) to Gallon (UK)/100mi

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

    Formula: gal (UK)/100mi = km/gal × 1,069.3066664751

    Reverse: km/gal = gal (UK)/100mi × 1,069.3066664751

    Step-by-Step Example

    1. Start with your value in Kilometer/Gallon (US). For example: 5 km/gal
    2. Apply gal (UK)/100mi = km/gal × 1,069.3066664751
    3. The result is: 213.861333 gal (UK)/100mi
