## Units

### Mile (mi)

An imperial unit of length equal to 5,280 feet or approximately 1.609 kilometers. The standard unit for road distances in the US and UK.

### Kilometer (km)

A metric unit of length equal to 1000 meters. The standard unit for measuring road distances and geographic distances in most countries.

## Background

A speed limit of 65 mph translates to about 105 km/h. A marathon at 26.2 miles is 42.195 kilometers. When renting a car in Europe, the speedometer reads in km/h, so knowing that 60 mph ≈ 97 km/h helps avoid speeding tickets. GPS devices switch between miles and kilometers depending on the country setting.

## Good to Know

Road signs in the US and UK show distances in miles, while virtually every other country uses kilometers. Canada switched to metric in the 1970s, so cross-border travelers between the US and Canada encounter the switch daily.

## FAQ

### How many kilometers are in 1 mile?

One mile equals exactly 1.609344 kilometers. For quick estimation, multiply miles by 1.6 for a close approximation.

### How do I convert miles to kilometers?

## Non-Frequently Asked Questions

### Is the 8 Mile movie about 12.875 kilometers?

Technically yes. 8 Mile refers to 8 Mile Road in Detroit, which is 12.875 km from downtown. But '12.875 Kilometer' would have been a terrible movie title. Eminem made the right choice.

### If I walk a mile, do I burn a kilometer's worth of calories?

You burn calories based on distance traveled, not what unit you use to describe it. Walking 1 mile burns the same calories as walking 1.609 kilometers, because they are the same distance. The calories do not care about your unit preferences.
