Kilometers per hour (km/h): A Unit of Measurement for Speed
Kilometers per hour (km/h) is a unit of measurement commonly used to express speed in countries that use the metric system. It represents the number of kilometers traveled in one hour.
The formal definition of kilometers per hour (km/h) is straightforward: it represents the distance traveled in kilometers divided by the time taken to travel that distance in hours.
For example, if a train travels a distance of 100 kilometers in one hour, its speed would be expressed as 100 kilometers per hour (km/h).
Conversions to Other Units of Measurement:
- Miles per Hour (mi/h): To convert kilometers per hour to miles per hour, multiply the speed in kilometers per hour by a conversion factor of approximately 0.621371. For example, 100 kilometers per hour is approximately equal to 62.1371 miles per hour.
- Knots (kts): Knots are commonly used in aviation and maritime contexts. To convert kilometers per hour to knots, multiply the speed in kilometers per hour by a conversion factor of approximately 0.539957. For example, 100 kilometers per hour is approximately equal to 53.9957 knots.
- Meters per Second (m/s): To convert kilometers per hour to meters per second, multiply the speed in kilometers per hour by a conversion factor of approximately 0.277778. For example, 100 kilometers per hour is approximately equal to 27.7778 meters per second.
- Feet per Second (ft/s): To convert kilometers per hour to feet per second, multiply the speed in kilometers per hour by a conversion factor of approximately 0.911344. For example, 100 kilometers per hour is approximately equal to 91.1344 feet per second.
- Mach: The Mach number represents the speed of an object relative to the speed of sound in the surrounding medium. Mach 1 is equal to the speed of sound. To convert kilometers per hour to Mach, divide the speed in kilometers per hour by the speed of sound in kilometers per hour. The speed of sound at sea level is approximately 1234.8 kilometers per hour. For example, if an aircraft is traveling at 1234.8 kilometers per hour, its speed is Mach 1.
Kilometers per hour (km/h) is a standard unit of measurement for speed, particularly in countries that use the metric system.
Miles per hour (mi/h): A Unit of Measurement for Speed
Miles per hour (mi/h) is a unit of measurement commonly used to express speed in countries that use the imperial system, such as the United States and the United Kingdom.
The formal definition of miles per hour (mi/h) is straightforward: it represents the distance traveled in miles divided by the time taken to travel that distance in hours.
Conversions to Other Units of Measurement:
- Kilometers per Hour (km/h): To convert miles per hour to kilometers per hour, multiply the speed in miles per hour by a conversion factor of approximately 1.60934. For example, 60 miles per hour is approximately equal to 96.56064 kilometers per hour.
- Knots (kts): Knots are commonly used in aviation and maritime contexts. To convert miles per hour to knots, multiply the speed in miles per hour by a conversion factor of approximately 0.868976. For example, 60 miles per hour is approximately equal to 52.13856 knots.
- Meters per Second (m/s): To convert miles per hour to meters per second, multiply the speed in miles per hour by a conversion factor of approximately 0.44704. For example, 60 miles per hour is approximately equal to 26.8224 meters per second.
- Feet per Second (ft/s): To convert miles per hour to feet per second, multiply the speed in miles per hour by a conversion factor of approximately 1.46667. For example, 60 miles per hour is approximately equal to 88 feet per second.
- Mach: The Mach number represents the speed of an object relative to the speed of sound in the surrounding medium. Mach 1 is equal to the speed of sound. To convert miles per hour to Mach, divide the speed in miles per hour by the speed of sound in miles per hour. The speed of sound at sea level is approximately 761.2 miles per hour. For example, if an aircraft is traveling at 761.2 miles per hour, its speed is Mach 1.
Miles per hour (mi/h) is a standard unit of measurement for speed, particularly in countries that use the imperial system.
