Why do scientists use the International System of Units (SI) ? A) so all scientists are guaranteed to come up with the same measurements B) so they can communicate their results without confusion C) because the tools scientists use only measure in SI units D) because the SI is based on the metric system

Answer: B) So they can communicate their results without confusion

Explanation: There are other systems besides the metric system, though the metric is the most commonly used system. In the SI international system, all units are derived from each other, forming a unique international standard. That way, all scientists around the world, or at least most of them using the SI system, can communicate in a unique scientific "language" without confusion and misunderstanding.
