OK, but I don't see why it fails for Boost.Units but not for Quan:
----------------------------------------------
#include <quan/length.hpp>
#include <boost/units/length_unit.hpp>
#include <iostream>
#include <cassert>

int main()
 {
    std::cout.precision(32);
// Quan
  quan::length::ft qft(3);
  std::cout << "quan qft.numeric_value() = "<< qft.numeric_value() << '\n';
  assert(qft.numeric_value() ==3);

// Boost.Units
  boost::units::feet f1(3);
  std::cout << "boost.units ft1.value() = " << f1.value() <<'\n';
  assert (f1.value() == 3);
}

-----------
output:

E:\projects\Test>testgcc
quan qft.numeric_value() = 3
boost.units ft1.value() = 3
assertion "f1.value() == 3" failed: file "test.cpp", line 17
