Odometer Miles to Kilometres Converter
Convert an odometer reading between miles and kilometres. Enter miles to get kilometres, or enter kilometres to get miles. Both fields update instantly. Also enter the vehicle's age to see average annual mileage in both units for comparison against typical market benchmarks.
Miles to kilometres conversion formula
Kilometres = Miles x 1.609344 (exact)
Miles = Kilometres / 1.609344
Avg annual miles = Total_miles / Vehicle_age
Avg annual km = Total_km / Vehicle_age
The conversion factor 1.609344 is exact and defined. It follows from the 1959 international yard agreement: 1 yard = 0.9144 m exactly, 1 mile = 1,760 yards, therefore 1 mile = 1,760 x 0.9144 = 1,609.344 m = 1.609344 km exactly.
Average annual mileage benchmarks
- US average (FHWA): about 14,000 to 15,000 miles/year (22,500 to 24,000 km/year).
- UK average (DfT): about 7,400 miles/year (11,900 km/year) for private cars.
- Australia average (BITRE): about 13,100 km/year (8,140 miles/year).
- Canada average (NRCan): about 15,200 km/year (9,445 miles/year).
- A vehicle at or below the market average for its age is typically priced at a premium; significantly above average mileage vehicles are discounted.
Odometer converter: frequently asked questions
How many kilometres is one mile?
Exactly 1 mile = 1.609344 kilometres. This is a defined exact conversion: in 1959, the international yard and pound agreement defined the international mile as exactly 1,609.344 metres. It is not an approximation. The conversion is also published in NIST Special Publication 330.
Why do I need to convert my odometer reading?
Vehicles imported from the United States or the United Kingdom read in miles, while most of the world including Canada, Australia, and the European Union use kilometres. When selling or buying an imported vehicle, converting the odometer reading helps compare it against local market listings. Some vehicle history reports and warranty documents also use different units depending on the country of origin.
What is considered high mileage in kilometres?
In the US, a vehicle with 100,000 miles (160,934 km) is generally considered high mileage. In km-based markets, 200,000 km is a common benchmark (equivalent to about 124,274 miles). Well-maintained modern vehicles can routinely exceed 300,000 km (186,411 miles). The key factors are service history and engine condition, not just mileage.
What is the average annual mileage in kilometres for international comparison?
The US FHWA reports an average of about 14,000 to 15,000 miles per year (22,500 to 24,000 km/year) for American drivers. Australian drivers average about 13,000 km/year per the BITRE. European drivers vary widely: UK drivers average about 17,000 km/year; German drivers about 15,000 km/year. These figures are useful benchmarks when assessing whether a used vehicle's mileage is above or below average for its age.
Can I verify the odometer reading on an imported vehicle?
In the US, the National Motor Vehicle Title Information System (NMVTIS) provides odometer history through participating history report providers. Odometer fraud (tampering) is a federal felony under 49 U.S.C. 32703 (the Motor Vehicle Information and Cost Savings Act). Sellers of used vehicles must provide written odometer disclosures on the title or a separate form under federal law.
