How to convert kilometers to miles
Formula: mi = km × 0.621371
Worked example: 5 km → 5 × 0.621371 = 3.10686 mi
To estimate quickly, multiply kilometers by 0.6, or use the Fibonacci trick: 5 km ≈ 3 mi, 8 km ≈ 5 mi, 13 km ≈ 8 mi. Race distances: a 5K is 3.11 mi, a 10K is 6.21 mi and a half marathon (21.0975 km) is 13.1 mi.
