Foot per Second to Kilometer per Hour
The speed conversion of 20 foot per second is ~21.94 kilometer per hour.
|Foot per Second||Kilometer per Hour|
In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.
