Henry should be represented as Volt/(Ampere/second) for obvious reasons. It measures the inverse of (d/dt Current)/Voltage.

Why is there a list of multiples? Aren't they just the standard SI prefixes?
It's there so that someone following a link from
microhenry or whatever will know why they are here. We used to have a bunch of articles about various prefixed units, but they were mostly removed (except in a few cases with special reasons for keeping them) and changed to redirects to the base unit. These redirects can now be linked to go directly to the section with the table showing what the linked prefixed unit or prefixed unit symbol means.

The unit conversion for newton may be off by m, rather than m^2 below
Sense of scale
It would be nice to add something to give a sense of scale. For example, include some pictures of some inductors.
How physically big are typical 1-henry inductors? What is the typical inductance of a inductor the size of your
small toe? How much would a 1-henry inductor cost? What about a milihenry?
Hard to put "typical" values in because reference weenies will pounce. Physical size depends on current rating and working voltage as much as inductance values. You'd expect "microhenry" values in the tuned circuits of radio-frequency circuits, but the field of a large DC motor might be many henrys. --
