BOOST_UNITS_DEFINE_CONVERSION_OFFSET
// In header: <boost/units/absolute.hpp>
BOOST_UNITS_DEFINE_CONVERSION_OFFSET(From, To, type_, value_)Macro to define the offset between two absolute units. Requires the value to be in the destination units e.g
BOOST_UNITS_DEFINE_CONVERSION_OFFSET(celsius_base_unit, fahrenheit_base_unit, double, 32.0);
BOOST_UNITS_DEFINE_CONVERSION_FACTOR is also necessary to specify the conversion factor. Like BOOST_UNITS_DEFINE_CONVERSION_FACTOR this macro defines both forward and reverse conversions so defining, e.g., the conversion from celsius to fahrenheit as above will also define the inverse conversion from fahrenheit to celsius.
