Answer:
a Metric System
Step-by-step explanation:
The International System of Units which is the current and revised metric system is widely accepted by all nations of the world with the exception of three countries namely, the United States of America, Liberia, and Myanmar. The metric system was initially the widely accepted standard and it was a set of measurement standards formulated by the French people during the French Revolution.
