Conversion

658 meters per second is equivalent to 2158.79265091863 feet per second.^[1]

Conversion in the opposite direction

The inverse of the conversion factor is that 1 foot per second is equal to 0.00046322188449848 times 658 meters per second.

It can also be expressed as: 658 meters per second is equal to $\frac{1}{0.00046322188449848}$ feet per second.

Approximation

An approximate numerical result would be: six hundred and fifty-eight meters per second is about two thousand, one hundred and fifty-eight point seven eight feet per second, or alternatively, a foot per second is about zero times six hundred and fifty-eight meters per second.

Units involved

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."

Feet Per Second

'The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s, or sec). The corresponding unit in the International System of Units (SI) is the metre per second.Abbreviations include ft/s, ft/sec and fps, and the rarely used scientific notation ft s−1.'
