How to Convert Miles per Hour (MPH) to Kilometers per Hour (KPH)

When working with vehicle speeds or analyzing transportation data, there is often a need to switch between standard miles per hour (MPH) and metric kilometers per hour (KPH). While MPH is commonly used in the US, most of the world uses the metric KPH system. This guide provides the basics for converting speeds between these units.

Understanding The Units

MPH measures the linear speed traveling a one-mile distance every hour. KPH quantifies kilometers traveled each hour instead, with a kilometer equaling 0.62 miles.

Some key reference speeds:

Unit Conversion Factor Highway Speed
MPH 1.61 KPH per MPH 65 MPH
KPH 0.62 MPH per KPH 105 KPH

So the units cover distance over time differently.

Performing the Speed Conversion

To transition between MPH and KPH measurements, you multiply or divide based on the metric conversion ratio:

KPH = MPH x 1.61 MPH = KPH x 0.62

Some example converted speeds:

| 70 MPH | = | 113 KPH | | 100 KPH | = | 62 MPH |

As shown, a higher MPH gives a higher KPH, while a higher KPH equals a lower MPH.

Key Takeaways

To summarize converting the speed units:

  • MPH measures miles distance traveled per hour
  • KPH quantifies kilometers traveled per hour
  • Use the conversions: KPH = MPH x 1.61 and MPH = KPH x 0.62
  • Adjustments match mile/kilometer differences
  • For mental math, multiply MPH by 1.5 to get KPH

So by applying the right conversion factor, MPH can easily convert to metric KPH or vice versa.

Type a value in the MPH field to convert the value to KPH:

Formula

KPH=MPH*1.609344

How to Convert Mile/hour to Kilometer/hour

1 mi/h = 1.609344 km/h
1 km/h = 0.6213711922 mi/h

Example:

convert 15 mi/h to km/h:
15 mi/h = 15 × 1.609344 km/h = 24.14016 km/h

convert 25 mi/h to km/h:
25 mi/h = 25 × 1.609344 km/h = 40.2336 km/h
