Miles to KM quick reference
| Miles | Kilometers |
|---|---|
| 1 mi | 1.61 km |
| 3 mi | 4.83 km |
| 5 mi | 8.05 km |
| 10 mi | 16.09 km |
| 13.1 mi (half marathon) | 21.08 km |
| 26.2 mi (marathon) | 42.16 km |
| 100 mi | 160.93 km |
How the conversion works
1 mile equals exactly 1.60934 kilometers. This tool uses that precise conversion factor, along with standard factors for meters, feet, and yards (1 mile = 5,280 feet = 1,760 yards = 1,609.34 meters), so results match official distance conversion charts handy for road trips, race distances, or map directions.
When you'll actually reach for this
The most common trigger is travel: renting a car in a country that posts distances in kilometers, reading a hiking trail sign abroad marked in km, or figuring out how far a European train route actually covers compared to a familiar US drive. Runners and cyclists use it constantly too US race culture is built around miles (5K aside), while most training apps, GPS watches, and international race results default to kilometers, so converting a pace or split between the two is routine. Geography and news also mix units freely; a storm's "50-mile-wide path" or a hurricane's distance offshore reported in km both need a quick mental conversion to make sense relative to somewhere familiar.
FAQ
Is this the same as the Length Converter?
No this tool is built for longer distances (miles, km, meters, feet, yards). For small, everyday measurements like height or screen size, use our Length Converter (cm, mm, inches, feet).
How many km is a marathon?
A marathon is 26.2 miles, which is about 42.16 kilometers. A half marathon is 13.1 miles, or roughly 21.08 kilometers.
Why is a nautical mile different from a regular mile?
A nautical mile (1.852 km) is longer than a statute mile (1.60934 km) because it's based on one minute of latitude rather than an old Roman land measurement this converter uses statute miles, the standard for road and land distances.
What's a quick way to estimate miles from km in my head?
Multiply kilometers by 0.62 (or divide by 1.6) for a close estimate so 100 km is roughly 62 miles. This tool gives the exact figure when you need more precision than mental math allows.
How far is a "5K" or "10K" race in miles?
A 5K is 5 kilometers, or about 3.11 miles. A 10K is 10 kilometers, or about 6.21 miles both distances are named in kilometers even in US races, unlike the marathon and half marathon.
Does this tool account for elevation or route distance, like a GPS track?
No this is a straight-line unit conversion of the distance value you enter. A GPS-tracked route's mileage already accounts for turns and elevation change; convert that resulting number here, rather than trying to convert straight-line map distance into a route distance.
