The easiest way would be to repeal the laws that forbid voluntary full
metrication and trade in metric only products.

For example, the FPLA is a Federal law covers packaged goods that you
see in the supermarket. It mandates non-metric units on the label. A
two liter bottle with a label that says "2 L" is legal in all
countries except the USA.

Many Americans are unaware that non-metric units are mandatory.

You bring up a good point. Let's face it, only Congress would know what is
best for us. We should do as the say.
