Enter the value that you want to convert speed.

Objective of Measurement:

Measurement is the most important aspect of our life. We use measurement in science, engineering, business trading, personal life, education, and more other fields. As technology is growing day by day so we need a highly accurate and easy convenient global measuring system in each and every field. It is essential to use standard measurement in every field that everyone to be sure that they not get cheated.

History of Measurement:

In history for measurement people used the human body as a tool. For measuring length used forearm, hand, foot & finger as a unit. The foot, finger is a subdivided shorter unit of a length. In the same way In 16th-century people used Dutchman's log method to know the speed of the ship. This type of measurement is not accurate cause different in size of the arm & finger for different people & some of the countries still using it. In history, there were lots of measuring systems developed but mostly used imperial, the metric system of measurement. We use these systems for measure distances, volume, weight, speed, area etc. Due to this a major problem everyone is facing while doing trading between the countries. A huge improvement in civilization, It necessary to improve measuring standards. Nowadays International Standard (SI) units are used as a global measurement system.

Speed - Unit Converter:

Our Unit Converter converts units of speed meter/second [m/s], kilometer/hour [km/h], mile/hour [mi/h], meter/hour [m/h], meter/minute [m/min], kilometer/minute [km/min], kilometer/second [km/s], centimeter/hour [cm/h], centimeter/minute [cm/min], centimeter/second [cm/s], millimeter/hour [mm/h], millimeter/minute [mm/min], millimeter/second [mm/s], foot/hour [ft/h], foot/minute [ft/min], foot/second [ft/s], yard/hour [yd/h], yard/minute [yd/min], yard/second [yd/s], mile/minute [mi/min], mile/second [mi/s], knot [kt, kn], knot (UK) [kt (UK)], Velocity of light in vacuum, Cosmic velocity - first, Cosmic velocity - second, Cosmic velocity - third, Earth's velocity, Velocity of sound in pure water, Velocity of sound in sea water (20°C, 10 meter deep), Mach (20°C, 1 atm), Mach (SI standard) to vice versa with a metric conversion. It specially designed to convert kph to mph, mph to kmh with a metric conversion table.
