Meter per Second

m/s

Definition

The meter per second is the SI base unit for speed and velocity, representing the distance traveled in meters divided by the time taken in seconds. It is the fundamental unit for measuring linear motion and is used extensively in physics, engineering, and scientific calculations worldwide.

History/Origin

The meter per second was established as part of the International System of Units (SI) in 1960, combining the meter (defined in 1791) and the second (based on atomic time standards). It replaced various regional speed units and became the standard for scientific and international measurements.

Current Use

Meter per second is widely used in physics laboratories, engineering calculations, sports science, automotive testing, and meteorological measurements. It provides precise measurements for velocity in scientific research, traffic engineering, and industrial applications.

Kilometer per Hour

km/h

Definition

The kilometer per hour is a unit of speed expressing the number of kilometers traveled in one hour. It is commonly used for measuring vehicle speeds, wind speeds, and general transportation velocities in most countries worldwide, except the United States.

History/Origin

Kilometer per hour became widely adopted with the metric system in the 19th century, particularly in Europe and other metric countries. It replaced various regional speed measurements and became the standard for road signs, speedometers, and official speed limits.

Current Use

Kilometer per hour is the primary speed unit for road traffic, aviation, maritime navigation, and weather reporting in metric countries. It is used on speedometers, road signs, weather forecasts, and in transportation planning and safety regulations.
