Sure, there would be interreset for such package in a lot of engineering
apps.
- I was worried about being limited to force, mass or acceleration. Can
you do compile time combination of units ?
Take this example, I have meters and seconds, I want to build speed
(ms^-1)
typedef si_units<double>::meter meter; // meter type
typedef si_units<double>::second second; // second type
// i build a new unit
typedef divide_units< meter, second > velocity; // velocity is
built from meter/second
- It would be nice also to merge this library with a "physical
constants" like gravity, and others...- do you plan to support other
units ? J, K, °C, mol, l, etc...
- did you think about a-dimensional units ? this is very common in fluid
mechanics.
Hoping to see files on yahoo :)

David -
Sorry for the slow response, but I think there is certainly an interest
in a
units library for boost. There have been several discussions, but
no one
willing to spend the time doing the work. Before spending too much
time
getting ready for formal review you will want to upload a
preliminary
submission for folks to evaluate and discuss. Typically libraries
get evolved
before they get reviewed and accepted.
