Explanation:

The International System of Units (SI) is the modern - form of the metric system and is a globally accepted measurement system. It is based on multiples of ten. The other options are incorrect as the SI is not used primarily only in France or Canada, and it is not a non - metric system with units like feet, pounds, and gallons.
