How do you convert miles per gallon (uk) to liters per 100km?

Divide 282.481 by the miles per gallon (uk) value. Formula: L/100km = 282.481 ÷ mpg (UK). For example, 34 mpg (UK) = 8.308265 L/100km.

How do you convert liters per 100km back to miles per gallon (uk)?

The same operation works in both directions: mpg (UK) = 282.481 ÷ L/100km. For example, 8 L/100km = 35.310125 mpg (UK).

Why do miles per gallon (uk) and liters per 100km move in opposite directions?

They are inverse measures of the same quantity — their product is always 282.481. A higher mpg (UK) value therefore always means a lower L/100km value, and doubling one halves the other.
