"a gigawat — a jillion watts
Funny, that's not the definition that I learned..."
In all fairness, the idiocy may actually lie with the interviewer, who could confuse billion with jillion. But there are plenty of other ridiculous errors...
I usually confuse a jillion with a gazillion.
A trillion electron-volts (eV) or 1x 10 to the 12th power (1E+12) is equal to 4.4504903611e-14 kilowatt-hours. That is a minus sign in front of the 14 so this is much less than one KwHr by a long shot. A kilowatt hour is the energy used to run a 100w light bulb for 10 hours. So, learning Physics from a business point of view does not learn you a lot of Physics.
