Should be:

http://klickverbot.at/code/units/std_si.html

One more thing: Angular units: I suggest non-SI-derived units for `Radian` and `Steradian` instead. Then, degrees and other derived angular units shall be expressed as scaled versions of these.

I don't see the point in defining these as meter/meter and meter^^2/meter^^2 in the type system.

Destroy!

Oops, already defined here:

Thanks, David.

Ohm my, that's awesome. Watt needs to happen to get this into Phobos?

have a look at this!

I'm cleaning up David's work right and will put up a PR today.

Could you briefly outline why you prefer this over David's work?

No module name in Phobos is currently in plural form. I suggest we stick to that standard a name these

std.experimental.unit
std.experimental.unit.si

One thing. How should these modules be represented on the file system?

Destroy!

std.traits
std.signals
std.typecons ;-)

std/experimental/unit/package.d
std/experimental/unit/si.d

For some other modules, Andrei has insisted that package.d must publicly import all subpackages, but I see no reason for this. std.experimental.unit can contain the basic general functionality, and std.experimental.unit.si the SI specific ones.

Is it able to manage quantities with a non-linear transformations, for example when dealing with octet and byte ?

(1024)!"byte" == 1!"kbyte";
