The Metric System
Three countries in the world do not use the metric system as the official system of measurement: the United States, Liberia, and Myanmar.
We inherited our current system of measurement from the English, who abandoned it over 50 years ago (in 1965).
The best thing we did was to involves our system for currency. We rejected their system and went to a metric system for currency.
However, I did not realize that we made a decision over 40 years ago to begin the process of officially converting to the metric system for measurements. Yep, that is true.
In 1975, the United States passed the Metric Conversion Act. The legislation was meant to slowly transition its units of measurement from feet and pounds to meters and kilograms, bringing the US up to speed with the rest of the world. There was only one issue: the law was completely voluntary.
