How to convert

km/h = mph × 1.609344. mph = km/h ÷ 1.609344 (about × 0.6214). Quick estimate: multiply mph by 1.6, so 50 mph is about 80 km/h.

Good to know

  • The number on a speed limit sign is in the unit used where you are. In the US that is mph, so read the sign as miles per hour and use this page only to get a feel for it in km/h.
  • Check which unit your speedometer shows (mph, km/h, or both). A rental or imported car may not match what you are used to.
