How Km to miles works

This converter turns kilometers into miles by dividing by 1.609344, the exact number of kilometers in one international mile. Type a distance and the result updates as you type, rounded to 12 significant digits, so 1 km shows 0.621371192237 mi. It uses the international statute mile of exactly 1,609.344 meters, not the nautical mile of 1,852 meters. It converts distances only, so running pace in minutes per kilometer needs a different calculation.

Before you start

Enter the distance as a plain number with a period for decimals, such as 42.195. Commas and unit labels typed into the box are rejected.

A worked example

Entering 42.195, the marathon distance, returns 26.2187574565 mi, and a 5 km race returns 3.10685596119 mi, usually rounded to 3.1 miles.

Continue your workflow: Length, Weight, Temperature.

Common questions

How many miles are in a kilometer?

One kilometer is 0.621371192237 miles, about 0.6214. The exact relationship runs the other way: one international mile is exactly 1.609344 kilometers, so the converter divides your kilometers by 1.609344.

Is there a quick way to convert km to miles in my head?

Multiply by 0.6 for a rough answer, or multiply by 5 and divide by 8 for a closer one. For 80 km, 80 × 5 ÷ 8 = 50 miles, while the exact result is about 49.71 miles. Both shortcuts slightly overstate the distance.

How many miles is a 10K or a half marathon?

A 10K is 10 km, which converts to 6.21371192237 miles, usually called 6.2 miles. A half marathon is 21.0975 km, which converts to 13.1093787282 miles, usually called 13.1 miles. A full marathon, 42.195 km, is about 26.22 miles.

Can I convert a pace in minutes per kilometer?

Not by dividing. Pace is time per distance, so you multiply instead: minutes per km × 1.609344 gives minutes per mile. A pace of 5:00 per km is about 8:03 per mile. Entering 5 in this converter would give 3.1 miles, which is a distance, not a pace.

Does this tool use nautical miles?

No. It uses the statute mile used on roads and in running, exactly 1,609.344 meters. A nautical mile, used at sea and in aviation, is exactly 1,852 meters, so 1 km is about 0.54 nautical miles.
