A quick mental shortcut
Multiply km by 0.6 and add a little (km × 5 ÷ 8 is closer): 80 km ≈ 50 mi. The Fibonacci trick also works — consecutive Fibonacci numbers (5, 8, 13, 21) are roughly miles and kilometers: 8 km ≈ 5 mi, 13 km ≈ 8 mi.
For road speeds rather than distances, use the km/h to mph converter.
