Kilometers to miles, the short of it
One kilometer is 0.621371 miles. Roughly five eighths of a mile. That ratio comes from the mile being defined as exactly 1.609344 km, flipped around. Whenever a distance shows up in kilometers and you measure your world in miles, this bridges the gap.
Drop a value in and the miles appear as you type. The math happens locally in your browser, so nothing gets uploaded and there’s no server in the loop.
Running races make this click
If you run, you’ve hit this conversion. Race distances are stubbornly metric almost everywhere. A 5K is 3.107 miles. A 10K works out to 6.214 miles. The half marathon, technically 21.0975 km, is 13.109 miles, and a full marathon (42.195 km) is the famous 26.219 miles.
Pace gets interesting here. If you run 5 minutes per kilometer, that’s about 8:03 per mile, since a mile is longer. Mixing up the two is how people end up confused about whether they’re getting faster.
Driving and speed limits abroad
Rent a car in Europe and the dashboard reads kilometers, the signs read kilometers, but your sense of distance might not. A 100 km drive is 62.1 miles, comfortably over an hour on a highway. When a sign says the next town is 30 km away, that’s 18.6 miles.
Speed limits trip up visitors constantly. A 120 km/h motorway limit is 74.6 mph. A 50 km/h urban limit is 31.1 mph. Plug in the number on the sign and you’ll know whether you’re cruising or crawling by your usual gauge.
Race distances, since that’s why most people land here:
- 5 km = 3.11 mi (the 5K, a parkrun staple)
- 10 km = 6.21 mi (the 10K)
- 21.1 km = 13.11 mi (half marathon)
- 42.195 km = 26.22 mi (full marathon)
Every other round number sits in the conversion table at the top of the page.
Driving the converter
Type kilometers into the input and the mile figure updates live, no button. The dropdown swaps either unit, so going miles to kilometers or switching to another distance unit keeps you on this page. The reference table at the top carries the values people look up most, races and round numbers included.
Results round to a practical precision. The underlying mile is exactly 1.609344 km, so for high precision you can work from that exact figure directly.
FAQ
How many miles in a kilometer?
0.621371 miles. A bit under two thirds of a mile. A quick estimate: multiply kilometers by 0.6 and you’re close.
How many miles is a 5K?
3.107 miles. It’s the shortest of the standard road races, which is why it’s the usual first-race distance. Double it and you’ve got a 10K at 6.214 miles.
How far is a 10K in miles?
6.214 miles. A 5K is exactly half that, 3.107 miles. Worth memorizing if you sign up for road races.
How far is a half marathon in miles?
13.11 miles, from the 21.1 km course (the exact distance is 21.0975 km, which rounds to 13.109). A full marathon is double, 42.195 km or 26.219 miles.

62.14 miles. A useful anchor: 100 km is about 62 miles, so you can scale most highway distances from there in your head.
Is the conversion exact?
The mile is defined as exactly 1.609344 km, so 1 km equals 0.621371 mi as the exact inverse, rounded for display. No measurement error, just truncated decimals.
