Shock and vibration specification are often made in g's, where g is the acceleration of standard gravity.
For testing and certification purposes, shock is specified by peak acceleration and the shape and duration of the pulse - e.g. 50g peak, 11 ms half sine.
Vibration specifications are either sinusoidal, specified by frequency and peak acceleration, or random. Random vibration is specified by a power spectral density, in g^2/Hz over a range of frequencies, for which an equivalent average can be stated in g's rms (root mean square, a common way of computing statistical averages).

I don't think that it should be different. If it is different what is it's value?
