Miles per Hour to Kilometers per Hour Converter
Convert Miles per hour to Kilometers per hour (mph to km/h) or Kilometers per hour to Miles per hour (km/h to mph)
Formula to Convert kph to mph and mph to kph
How many Kilometers Per Hour to Miles Per Hour?
- To convert Kilometers per hour to miles per hour, multiply by 0.62
Miles Per Hour = 0.62 * kph - For example, to convert 150 kilometers per hour to miles per hour, multiply 150 by 0.62
miles per hour = 0.62 * 150 kmh = 93.2 mph
150 km/h is equal to 93.2 mph
How many Miles per hour to Kilometers per hour?
- To convert Miles per hour to Kilometers per hour, multiply by 1.61
km/h = 1.61 * mph - For example, to find out how many kilometers per hour for 75 miles per hour, multiply 75 by 1.61
kilometers per hour = 1.61 * 75 mph = 120.7 kmh
75 mph is equal to 120 km/h
What is Kilometers Per hour?
- Kilometers per hour is a unit of speed in the metric system.
- It measures the distance travelled by a moving object in an hour. Distance covered is measured in kilometers.
- Though widely used in many countries that follow metric system, it is not the standard unit of speed. The SI Unit of speed is meters per sec (m/s)
- The unit for kilometers per hour is km/h. Other abbreviations such as kmh, kph or kmph is also commonly used.
Usage of kilometers per hour.
- Vehicle speeds are typically expressed in kilometers per hour.
- Speed of Animals and Birds
- Walking, Running, Jogging and Swimming Speed of Human beings and events
- Wind Speeds such as Cyclones are expressed in km/h
- Speed of earth and all moving astronomical objects
What is Miles Per hour?
- Miles per hour is a unit of speed in the imperial system.
- The imperial system is mostly followed in US where miles is used instead of kilometers for distance and length measurements.
- Miles per hour is the distance travelled by an object in an hour where distance is in miles.
- The unit for miles per hour is mph.
Usage of Miles per hour
- Vehicle speeds, speedometer, speed limits are all in mph
- Windmill, Turbine speeds
- Speed of animals, birds, human beings,
- Events such as marathon, running race, car race, swimming race
- Wind Speed such as Hurricane, Tornado, Typhoon

1 km per hour = 0.621 miles per hour .
1 mile per hour = 0.447 meters / sec.
1 km per hour = 0.277 meters/sec
Most countries use the metric system (kms, meters) while the US uses miles per hour.
This is the System international (SI) unit for measuring speed.
It is the standard measurement.
Miles and Kilometer are units of distance.
Miles per hour (mph) and kilometers per hour (kmh or kph) are units of speed in the metric system which is the distance travelled in a specified duration of time.
Speed (in mph) = Distance travelled (in miles) / Time (in hours) .
Speed (in kph) = Distance travelled (in kms) / Time (in hours) .
The SI unit for speed is in meters/second.
Knot is used as measure of speed in sea (1 nautical mile per hour).
Nautical mile measures distance in sea.
1 Knot is equal to 1.15 miles per hour and 1.85 kms/hour.
Mach is used in aviation as a percentage to speed of sound .
An average human walking speed is 3 miles per hour (around 5 kms/hour and 1.3 meters/sec)
The fastest clocked in a running rac is 27.5 mph (44.25 kms/hour and 12.3 m/s).
The average running speed of human beings will be the range of 5-6 mph.
Speed of light 299,792,458 metres per second or 300,000 kms / hour, 186451.21 miles per hour .
Speed of sound 343 meters / sec, 1234.8 kms / hr, 767 miles per hour .
Mach is the (speed of object / speed of sound). It is mostly used in aviation .
1 Mach = speed of sound which is 332 m/s or 1195 km/hr or 717 miles/hour .

Hypersonic between 5.0 - 10.0 Mach .
The SI Unit of both speed and velocity is meters/sec.
Speed is a scalar unit and it measures the distance covered over a period of time.
Velocity is the net displacement over a period of time.
If a person walks 100 steps eastward in 1 min and 100 steps westward in 1 min, then net displacement is 0 and velocity is 0 .
