How to Convert Miles per gallon (US) to Gallon (UK) per 100 miles

Converting Miles per gallon (US) (mpg (US)) to Gallon (UK) per 100 miles (gal (UK)/100mi) 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 (US) equals 83.267418 Gallon (UK) per 100 miles, while 1 gal (UK)/100mi equals 83.267418 mpg (US).
