Kilometre per hour [km/h] to Metre per second [m/s] Converter

Definition: Kilometre per hour (km/h) is a unit of speed, expressing the number of kilometres travelled in one hour. It is commonly used for measuring the speed of vehicles, especially in countries that use the metric system.

History/origin: Kilometre per hour is derived from the metric system, based on the kilometre as a unit of distance and the hour as a unit of time. It became popular as countries adopted the metric system for standardization.

Current use: Km/h is widely used in road signage, vehicle speedometers, and weather reports in many countries. It is a practical unit for expressing speeds within a human-scale context, such as driving or cycling.

Definition: Metre per second (m/s) is the SI derived unit of speed or velocity, expressing the number of metres travelled in one second. It is a fundamental unit in physics and engineering.

History/origin: The metre per second is derived from the base SI units of length (metre) and time (second). Its adoption is linked to the standardization of units during the French Revolution, leading to the establishment of the metric system.

Current use: M/s is used extensively in physics, engineering, and everyday life for measuring speeds of objects, such as vehicles, projectiles, and wind. It is also used in scientific calculations involving motion.
