To convert miles per hour (mph) to kilometers per hour (km/h), multiply by 1.609344 — e.g., 60 mph becomes 96.56 km/h.
How do you convert h to KM?
Multiply mph by 1.609344 to get km/h.
Say you’re driving at 55 mph. Just punch 55 × 1.609344 into your phone’s calculator (or ask Siri) and you’ll get 88.51 km/h. That’s because one mile equals about 1.61 kilometers — a fixed ratio you can trust. Most modern cars and GPS units let you toggle between mph and km/h anyway, so you rarely need to do the math yourself.

In countries where km/h is the norm, 160 on the dial is a gut-check moment — time to lift your foot before the dashboard lights up like a Christmas tree.
