978 kilometers per hour in meters per second

Result

The conversion result is: 978 kilometers per hour is equivalent to 271.666666666667 meters per second.^[1]

Conversion in the opposite direction

The inverse of the conversion factor is that 1 meter per second is equal to 0.00368098159509202 times 978 kilometers per hour.

It can also be expressed as: 978 kilometers per hour is equal to 1 / 0.00368098159509202 meters per second.

Approximation

An approximate numerical result would be: nine hundred and seventy-eight kilometers per hour is about two hundred and seventy-one point six seven meters per second, or alternatively, a meter per second is about zero times nine hundred and seventy-eight kilometers per hour.

Units involved

This is how the units in this conversion are defined:

Kilometers Per Hour

"The kilometer per hour is a unit of speed, expressing the number of kilometres travelled in one hour. The unit symbol is km/h. Worldwide, it is the most commonly used unit of speed on road signs and car speedometers."

Meters Per Second

"Meter per second is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.The SI unit symbols are m·s−1, m s−1, m/s, or m/s, sometimes (unofficially) abbreviated as mps. Where metres per second are several orders of magnitude too slow to be convenient, such as in astronomical measurements, velocities may be given in kilometres per second, where 1 km/s is 1000 metres per second, sometimes unofficially abbreviated as kps."
