12429	CGS unit of current is not well defined in reference ot Ampere	alfredo.correa@…	Matthias Schabel	"1 biot (cgs unit of current) is converted to 0.1 Ampere. It should be 10 Ampere.


{{{
#include <boost/units/systems/cgs/io.hpp>
#include <boost/units/systems/si/io.hpp>
#include <iostream>
using std::cout;

int main(){

	using namespace boost::units;

	cout << 1.*cgs::biot << "" = "" << quantity<si::current>(1.*cgs::biot) << '\n'; // not ok! ""1 Bi = 0.1 A""
	cout << 1.*cgs::centimeter << "" = "" << quantity<si::length>(1.*cgs::centimeter) << '\n';
	cout << 1.*cgs::gram << "" = "" << quantity<si::mass>(1.*cgs::gram) << '\n';
}

}}}


The solution is change -1 by 1 in ""boost/units/base_units/cgs/biot.hpp""

from 

{{{
typedef scaled_base_unit<boost::units::si::ampere_base_unit, scale<10, static_rational<-1> > >

}}}
to 


{{{
typedef scaled_base_unit<boost::units::si::ampere_base_unit, scale<10, static_rational<1> > >
}}}
