How to Convert Miles to Kilometers

Distance: miles (mi) ↔ kilometers (km).

The formula

1 mile = 1.609344 km (often rounded to 1.609). So:

km = miles × 1.609

To go from km to miles: miles = km ÷ 1.609 (or multiply by ~0.6214).

Examples

• 5 miles ≈ 8.05 km
• 10 km ≈ 6.21 miles
• 26.2 miles (marathon) ≈ 42.2 km

Quick approximation

For a rough estimate: 5 miles ≈ 8 km, so “miles × 8⁄5” gives a close km value. Or “km × 5⁄8” for miles.
