Global Fuel CalculatorKilometres to Miles Converter
Planning a drive where the satnav speaks kilometres but your cost or mileage figures use miles? Enter the kilometres and get miles back, using the exact international definition of the mile instead of an approximation.
A quick mental shortcut is to multiply by 0.6. That's fine for a rough guess but it drifts on longer trips: 500 km is 310.7 miles, not 300. For fuel budgeting, where small errors compound, the exact figure is the better habit.
