U

Commercial unit of heat flow (thermal conductance), reciprocal of R.

When the U.S. dollar is weak, U.S. manufacturers have a competitive advantage -- they don't have to lower prices on exports to boost sales and capture market share overseas. Just by keeping prices steady, they benefit because the weak dollar means foreign buyers won't have to pay as much in their respective currencies. The profit margin on each unit is constant, so earnings go up. (from November 2004)
