Conclusion
1. Explain the meaning of significant digits (or significant figures) in measurement.
It allows for you to know what's certain and what is estimated.
2. Why is the metric system used instead of the US customary system, and vice versa, in various parts of the world?
Because the metric system is on a base 10 decimal system so the numbers are related as opposed to the customary system in which the numbers have no relation.
