• Kilometers per hour is a unit of speed. It measures the number of kilometers an object travels within an hour.

• Miles per hour is a unit of speed in the imperial system.

• The SI unit of speed is meters per second (m/s)

## A Note on Miles Per hour to Kilometers Per Hour

• The conversion factor between mph and km/h is 1 mph = 1.609344 km/h.
• To convert mph to kph, you can multiply the mph value by 1.609344.
• For example, if a car is traveling at 60 mph, the equivalent speed in km/h would be 96.56 km/h (60 * 1.60934).
• To convert kph to mph, you can divide the kph value by 1.609344.
• The conversion from miles per hour (mph) to kilometers per hour (km/h) is commonly used in countries that use the metric system, as km/h is the standard unit for measuring speed.
• The mph to kmh conversion is important for international travel and navigation, as different countries use different units to measure speed. Being able to convert between mph and km/h allows for easy understanding and comparison of speeds across different regions.
• The United States is one of the few countries in the world that still uses mph as the standard unit of speed measurement. This is part of the imperial system of measurement.
• Most other countries use km/h which is part of the metric system . Therefore, understanding the mph to km/h conversion is for those working with international speed limits.
• It's interesting to note that kilometers per hour to miles per hour conversion factor is derived from the ratio between the length of a mile (1.60934 kilometers) and the length of a kilometer (0.62137 miles). This reciprocal relationship allows for a straightforward conversion between the two units.
• The kph to mph conversion is not limited to speed measurements but can also be applied to other forms of velocity, such as wind speed, running pace,
• Here are some interesting trivia on mph to kmh conversions:
• The speed of sound is approximately 767 mph or 1234 km/h at sea level.
• The speed of light is approximately 671 million mph or 1.08 billion km/h
• The world's fastest land vehicle, the ThrustSSC, reached a speed of 763 mph or 1228 km/h in 1997.
• The world's fastest production car, the Bugatti Chiron Super Sport 300+, reached a speed of 304.773 mph or 490.921 km/h in 2019.
• The average speed of a commercial airliner is approximately 575 mph or 925 km/h.
• The fastest human ever recorded was Usain Bolt, who reached a speed of 44.72 km/h (27.82 mph) in the 100-meter dash at the 2009 World Athletics Championships.

### Frequently Asked Questions on kmh mph Converter

• Mile is a bigger unit than Kilometer. 1 mile per hour = 1.609 kms per hour . 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 . Supersonic 1.2 – 5.0 Mach . 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 .
