In the Netherlands (and most of Europe), you would write one thousand million watts as 1.000 megawatts.
The decimal indicator in Europe is a comma. For example, 1,5 means one and a half 1.000.000 means one million.

Hi Sil, ZL2CIA
In Italy you would write one thousand million watt as 1000 megawatt or alternatively 1000 MW
In addition the units in Italy are written without plural and to write megawatts is wrong in Italy but the plural is used in England and USA
In any calculator 1.5 means one and half because the calculators are not using comma.
In any calculator 1000000. means one million
I thing that the best for everybody should be to write numbars as any calculator shows.

I think we should all use hexidecimal. Or binary :)

There is also the group of Virtucons who use gagillion, fafillion, shabolubalu million illion yillion, when describing lasers.
I believe this was first described in a movie with Mr. Myers.

I tell my electronics students that we can express gain or loss in dB by taking the log of power ratios and multiplying by 10, or by taking the log of the voltage or current ratios and multiplying by 20.
If we multiply the log by 16 instead, then the result is expressed in hexadecibels. :-)
("Hexabels" sounds too much like a made-up word.)
