An accelerometer is an instrument to measure acceleration, which is the change in velocity per unit of time.
Speed. Kilometre measure distance, and hour is a measure of time. Distance / Time = Speed.
feet per second per second ft/(sec2) or any distance unit and any time unit.
Measure the speed at two different points in time. Then take your first value and subtract the second value. A positive value means a gain in speed, a negative number is a decrease in speed, and a value of 0 means no change in speed. The value itself represents how much it has changed. To describe the the change as acceleration you need to divide the change in speed in meters per second, by the time it took in seconds. The SI unit for acceleration is meteres per second per second.
However you want: Speed is a measure of units of distance per units of time. Miles per hour or meters per second are common ones.
It is not.913 miles per hour is a measure of speed while kilometres are a measure of distance. To get speed you need a unit of time. The SI unit is a second, so using that as the unit of time,913 miles per hour is 0.408 kilometres per second.It is not.913 miles per hour is a measure of speed while kilometres are a measure of distance.

m/s/s or m/s2 aka meters per second per second or meters per second squared
Constant velocity is, well, constant. To measure it, measure the displacement through a given or fixed period of time. You'll have distance and time. Distance per unit time is speed. Distance per unit time (speed) with a direction vector is velocity. Velocity is speed in a given direction. If something is moving at constant velocity, it is moving at a constant speed in one direction. No changes in speed (no positive or negative acceleration, or, said another way, no acceleration at all), and no change in direction or heading.
speed
Speed, or velocity, is measured in distance per second; it is the rate of change of distance with time.Acceleration is the rate of change of velocity with time, or distance per second per second, which is distance per seconds squared,
This is acceleration (or deceleration)
Speed can regard two approaches. In velocity speed is the change in distance over time. In SI units speed is measured in meters per second. Speed can also measure the rates of reactions in the physical sciences and computations in computer sciences.
Distance and time are the two factors that speed depends on. The definition of Speed is change in Distance per change in time. S=D/t.
