428 feet per second in meters per second

Conversion

428 feet per second is equivalent to 130.4544 meters per second.^[1]

Conversion in the opposite direction

The inverse of the conversion factor is that 1 meter per second is equal to 0.00766551377339515 times 428 feet per second.

It can also be expressed as: 428 feet per second is equal to $\frac{1}{0.00766551377339515}$ meters per second.

Approximation

An approximate numerical result would be: four hundred and twenty-eight feet per second is about one hundred and thirty point four four meters per second, or alternatively, a meter per second is about zero point zero one times four hundred and twenty-eight feet per second.

Units involved

This is how the units in this conversion are defined:

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.'

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."
