all countries have mixed economies
The most important reason is concern that the value of the currency will be more easily affected by factors outside the country's control.

It is to provide a simple and coherent system of measurement units which are agreed by all people. Unfortunately, the US, Burma and Liberia have failed to adopt it.
The National Convention voted to adopt the metric system of measurement during the era of revolution and reform in France.
Most totalitarian countries have a dictatorship by a despot who holds onto power. Most, but not all totalitarian countries adopt this economic system.
In case I read the question wrong, I am assuming you asked Where is the metric system commonly used instead of English units. The answer is everywhere EXCEPT America. The metric system is an international measurement system based on 10. France was first to adopt it in 1799 and it is now the basic measurement system used in almost every country in the world. The United States has yet to adopt it which is why American products, highway speeds ....virtually everything is still in standard English measurement. It is very very slowly coming into use commonly in America. It is incredibly easy to use, but in school you are taught conversion, which is hard, and absolutely unneccessary. This turned many people off to it.
There are a large number of countries using the PAL system - Wikipedia has a map of the world showing which countries adopt this system for TV. See related link for more info.
Not specifically.
The United States of America is the only industrialized country that does not use the metric system as its primary system of measurement. Of course, scientists use the metric system even in the USA. But most Americans use the English system instead.
It made it so much easier to communicate with, trade with, buy from, and sell to the 200-or-so other countries in the world that use the same system. Note to the USA . . .
The unitary system of government is typically adopted because it is a more cost efficient system. Not only is it more modestly priced, but it is also very economical in terms of personnel and material resources.
