Why do scientists use the metric system (SI units) in scientific research?

• A. Because it provides a standardized and universally accepted system for measurements.
• B. Because it is the oldest measurement system in the world.
• C. Because it uses larger units that are easier to work with.
• D. Because it is only used in chemistry and not in other sciences.

Answer: (A)

Verified step by step guidance

1. Understand that the metric system, or SI units, is a standardized system of measurement used worldwide in science.
2. Recognize that having a universal system allows scientists from different countries and disciplines to communicate and compare results accurately.
3. Note that the metric system is based on powers of ten, which simplifies calculations and conversions between units.
4. Realize that the metric system is not the oldest system, nor does it use only larger units; it includes a range of units suitable for various scales.
5. Conclude that the primary reason scientists use the metric system is because it provides a standardized and universally accepted system for measurements, ensuring consistency and clarity in scientific research.
