New US President Obama should complete the metrication of the USA as soon as possible.
The USA started off using metric at one time. But over time, the silly old imperial units gained more prominence, becoming known as "English" units, despite being different in their definitions to those used in England, even though most of the world was changing to metric.
Why stay in the dark ages with US Customary Units? If Obama wants change, the way forward is metrication now.
