Liters per 100km to Miles per Gallon (UK) Formula & Unit Definitions
The conversion between volume consumed per distance (L/100km) and distance traveled per volume (MPG UK) follows an inverse curve dictated by the physical constants of the metric kilometer and the Imperial gallon. The constant 282.480936 is calculated as (100 km × 4.54609 L/gal) ÷ 1.609344 km/mi = 282.480936. Dividing 282.481 by the L/100km rating yields the exact UK MPG equivalent: MPG (UK) = 282.481 ÷ (L/100km).
Quick Estimation: Quick mental shortcut: To convert L/100km to UK MPG in your head, divide 280 by the L/100km figure. For example, 280 ÷ 7 L/100km = 40 mpg UK (exact: 40.35 mpg UK); 280 ÷ 5 L/100km = 56 mpg UK (exact: 56.50 mpg UK).
Liters per 100 Kilometers — L/100km
Continental Metric Standard- Standard fuel consumption measure across the European Union and UNECE vehicle regulations
- Directly quantifies the exact volume of liquid fuel consumed over a standard distance of 100 km
- Lower numerical ratings signify cleaner, more cost-effective vehicle operation
Miles per Gallon (UK) — mpg UK
British Customary Standard- Official metric prescribed by the UK Vehicle Certification Agency (VCA) and motoring press
- Calculated as statute miles (1,609.344 meters) traveled per British Imperial gallon (4.54609 L)
- Higher numerical figures indicate superior vehicle efficiency and extended driving range
