When you'll use this
- Converting US road-trip mileage into km for a European GPS app, Strava segment, or rental car dashboard
- Understanding a US marathon training plan (miles) in the km terms used by most of the world
- Comparing a US commute distance to a metric-based public transit or cycling map abroad
- Converting a US highway speed limit sign's implied distance context for an international visitor
- Estimating a hiking trail's length when US trail guides use miles but your GPS watch logs km
Practical note
Runners moving between US mile-based training culture and the rest of the world's kilometer-based races use this page heavily: a 3-mile training run converts to about 4.83 km, which matters when a GPS watch or race app is set to metric. It is equally common for road trips — 250 miles converts to roughly 402 km, useful when reading a European map, planning fuel stops in a rental car with a km-based trip computer, or comparing a US flight distance to an international route reported in kilometers by foreign airlines and news outlets.
Tips
- A mile is exactly 1.609344 km, so this conversion has zero rounding error — only the display precision you choose introduces any rounding.
- If you train with a US mile-based plan but a km-based watch, converting your target pace (e.g., an 8-minute mile) helps you set an equivalent km-based pace alert.
- "5K" and "10K" races are named for kilometers, not miles — a 5K is 3.1 miles, easy to forget if you grew up with mile-based track events.
