Just wanted to clarify something. These should convert from given quantities to the desired units?
If what you really want is a raw double, than, yes, this should work.
double unit_conversion::from_length_to_inches(quantity<length> const & L) { const quantity<inch_base_unit::unit_type> result_(L); return result_.value(); }
double unit_conversion::from_mass_to_pounds(quantity<mass> const & M) {
Pounds is a unit of force, not mass. To do such a conversion, you need to multiply by g.
Pound-force (literally, "lbf") or pounds (i.e. "lb")? Interestingly enough, I may also need to work in Pound-force, or a neighboring unit, i.e. "slugs.ft/s" http://en.wikipedia.org/wiki/Pound_(mass) http://en.wikipedia.org/wiki/Pound_(force) Would you mind disambiguating that in terms of Boost.Units? As far as I can tell from the US base unit (BOOST_UNIT_SYSTEMS_US_POUND_HPP_INCLUDED), we're talking about Mass in this instance. Thank you...
const quantity<ounce_base_unit::unit_type> result_(M); return result_.value(); }
In Christ,
BTW, did you find the PR okay for next version(s) of Units and/or Boost?
