Miles to Kilometers Converter

About Distance Conversion

Converting miles to kilometers? This is one of those conversions you'll use constantly if you travel, run, or just try to understand distances outside the US. Miles are the standard for distance in America, but pretty much everywhere else uses kilometers.

A mile is 5,280 feet, or exactly 1.609344 kilometers. That 1.6 number is close enough for quick estimates—just multiply miles by 1.6 and you're in the ballpark. Five miles is about 8 kilometers. Ten miles is roughly 16 km. For exact calculations though, you need the full conversion, and that's where this tool comes in handy.

Kilometers are the metric standard worldwide. One kilometer equals 1,000 meters. It's part of that clean decimal system where everything's based on multiples of 10. In most countries, road signs, maps, and GPS systems show distances in kilometers. The US is basically the only place still using miles for everyday distance measurements.

Travel is where this conversion matters most. If you're driving in Canada or any European country, road signs show kilometers. A sign saying the next town is 50 km away means about 31 miles. Speed limits too—you'll see 100 km/h on highways, which is roughly 62 mph. Understanding kilometers helps you navigate and drive safely when you're abroad.

Road trips across borders get interesting. You might start in the US where everything's in miles, then cross into Mexico or Canada where it switches to kilometers. Your car's odometer might be in miles, but the road signs are in kilometers. Being able to convert on the fly helps you figure out how far you've gone and how much further you need to travel.

Running and fitness tracking involves this constantly. Races are almost always measured in kilometers outside the US. A 5K race is 5 kilometers (about 3.1 miles). A 10K is 10 kilometers (roughly 6.2 miles). Marathon distance is 42.195 kilometers, which is 26.2 miles. If you're training for an international race or following a training plan from another country, you'll need to convert between units.

Even if you're running in the US, some apps and trackers let you switch between units. Maybe your watch shows kilometers but you think in miles. A 5-mile run is 8.05 km. A half marathon is 13.1 miles or 21.1 km. Converting helps you understand your pace and distance regardless of which unit you prefer.

Cycling is the same deal. Bike routes, especially in Europe, are measured in kilometers. That 100 km bike route sounds long, but it's about 62 miles. Tour de France stages are measured in kilometers—a 200 km stage is roughly 124 miles. Understanding both units helps whether you're planning a route or just watching professional cycling.

Navigation and GPS systems often let you choose your preferred unit. But if you're following directions from someone or looking at a map from another country, you might need to convert. "Turn left in 2 kilometers" means about 1.24 miles ahead. Being able to convert helps you anticipate turns and plan your route.

Fuel efficiency gets interesting too. In the US, we measure in miles per gallon (mpg). Most of the world uses liters per 100 kilometers. The conversions can be tricky, but knowing that a car that gets 30 mpg is roughly equivalent to 7.8 liters per 100 km helps when comparing vehicles from different markets.

Aviation uses nautical miles (which are different from regular miles), but sometimes you'll see distances in kilometers depending on where you're flying. Understanding the conversion helps when reading flight information or planning trips.

Even daily conversations about distance can involve this. Someone might mention they live 10 miles from work, but if you're from a metric country, that doesn't mean much. Converting to 16 km helps you understand. Or you're telling someone about a hike you did—was it 5 miles or 8 kilometers? They're basically the same distance, just different units.

Sports beyond running use kilometers too. Cross-country skiing, hiking trails, bike paths—they're often marked in kilometers. Understanding the conversion helps when you're looking at trail maps or planning outdoor activities internationally.

This converter makes it simple. Type in miles, get kilometers instantly. No mental math, no estimating. It works offline so you can use it anywhere, even when you're out of cell range on a road trip. Free, straightforward, and does exactly what you need—converts miles to kilometers without any fuss.
