kilometer per hour
- Definition: Kilometer per hour (km/h) is a unit of speed that expresses the distance traveled in kilometers over the span of one hour.
- Symbol: The commonly used symbol for kilometer per hour is “km/h.”
- Usage: This unit is widely used around the world to indicate the speed of vehicles, such as cars, trains, and bicycles, and is a standard measurement in countries that utilize the metric system.
yard per hour
- Definition: Yard per hour (yd/h) is a unit of speed that represents the distance covered in yards over the duration of one hour.
- Symbol: The symbol for yard per hour is “yd/h.”
- Usage: This unit is primarily used in the United States and some other countries that still use the imperial system, often for measuring the speed of machinery or in certain sports contexts.
Origin of the kilometer per hour
- The origin of the kilometer per hour is rooted in the metric system, which was developed in France during the late 18th century. The kilometer itself is defined as 1,000 meters, and the hour is a standard time unit. This metric speed measurement became widely adopted globally, particularly in countries that use the metric system for most measurements.
Origin of the yard per hour
- The yard as a unit of length has historical roots dating back to ancient times, with origins in various European measuring systems. The yard was standardized in England in the 14th century, and the yard per hour developed as a speed measurement from this unit. It remains in use primarily in the United States and a few other locations that utilize imperial measurements.
