"What are the measurements of power, as in kilowatts, megawatts, gigawatts."
Not sure what your asking but,
kilo = thousand 1x10^3
mega = million 1x10^6
giga = billion 1x10^9
Where power is measured as the area under a particular shaped pulse of energy, at a given frequency (duration of the pulse of energy). Beyond this explaination it would require to much writing.
