Speed is a measure of distance traveled per unit of time. Speed has units of meters per second for distance in a straight line. Speed has the same dimension as speed, and has the same unit as distance divided by time, so one can also be measured in terms of the other. The average speed of an object is the distance traveled per unit time. Speed can be thought of as the rate of change of position with respect to time.

SI unit of speed is meter per second (m/s) but many other unit mile per hour, Kilometer per hour, Feet per Hour, Feet per second, Centimeter per second, Centimeter per hour, Kilometer per hour, Knots, Mach, Centimeter per second, Centimeter per minute.

A knot is a unit of speed equal to one nautical mile per hour, approximately 1.151 mph. The international standard symbol for knot is kn, which is also the SI symbol for the cask (or hogshead) of wine. The term "knot" is also used to refer to some lengths other than the nautical mile.

Mach is a unit used to measure the speed of sound. It is named after the Austrian physicist Ernst Mach. The speed of sound varies depending on the medium through which it travels. In dry air at 20 °C (68 °F), the speed of sound is approximately 343.2 m/s (7687 ft/s). In water, it is about 4,000 m/s (9,800 ft/s). In solids, the speed of sound is slower than in air, and varies with the square of the atomic number of the material. The speed of sound in a gas is only slightly dependent on temperature, increasing by about 0.6 m/s for each degree Celsius increase in temperature.
