Measure system SI

Introduction

The International System of Units, the SI is a decimal and metric system of units established in 1960 and periodically updated since then. The SI has an official status in most countries, including the United States and the United Kingdom, with these two countries being amongst a handful of nations that, to various degrees, continue to resist widespread internal adoption of the SI system. As a consequence, the SI system “has been used around the world as the preferred system of units, the basic language for science, technology, industry and trade.”
