Examples

So, for example, a force adequate to lift one pound a distance of one foot is a footpound; that capable of lifting one kilogram a distance of one meter is a kilogrammeter, etc.

Someone can please correct me on this if I am in error, but here's what I come up with: a volt is defined as the difference in electric potential that is required to impart to 1 coulomb of electricity a kinetic energy of 1 joule = 1 newtonmeter = 1 kilogrammeter/second/second = 1 wattsecond, and since there are 6.24 x 10 to the 18th power electrons in a coulomb (according to Wikipedia, of course), this means that 1 electronvolt = 1/(6.24E18) = 1.60 times 10 to the minus 19th power wattsecond.
