A new alpha version of mcs::units has been posted to
SourceForge since the vault is not accepting uploads:

www.sourceforge.net/projects/mcs-units

(mcs_units_v0.7.0_alpha_4.zip). This version includes
some significant new functionality that Steven Watanabe
and I have been working on:

- heterogeneous and mixed unit systems allowing
constructs such as watt hr, m^2/cm^(1/2), etc... in
which fundamental units from different unit systems
are combined and multiple fundamental units may
have the same dimensional signature.

- fine-grained implicit unit conversion has been
enabled, allowing implicit conversions as long as
they are allowed for every fundamental dimension
present

- conversions between homogeneous and heterogeneous
unit systems

- trigonometric functions and angle systems for degrees,
gradians, and radians (with implicit conversions to SI and
CGS radians) are included

- a nearly complete set of CODATA physical constants

Comments and bug reports (especially on the heterogeneous
unit/implicit conversion functionality) are welcomed, as always.
Documentation is not completely up to date, but virtually all
functionality is demonstrated in the examples.
