It may be helpful for you to know how to calculate the "band" that hams are always talking about. It is really the wavelength of the frequency (in meters):
Wavelength = 300/fMHz
So our 29 MHz frequency that we call 10 meters comes from 300/29 which is approximately 10. We tend to round the wavelength to some convenient number.
For your 462 MHz GMRS example, it becomes a fractional number: 300/462 is approximately 0.65 meters. So we would tend to call this 65 centimeters (65 cm). The closest ham band to this is 70 cm.
