Why do scientists prefer to use the metric system (SI units) for scientific measurements?

• A. Because the metric system uses larger units, which are better for scientific work.
• B. Because the metric system is only used in Europe and not recognized internationally.
• C. Because SI units are based on powers of ten, making calculations and conversions easier.
• D. Because SI units are more accurate than any other system.

Answer: (C)

Verified step by step guidance

1. Understand that the metric system, or SI units, is designed to be a universal system of measurement used worldwide in science.
2. Recognize that one key advantage of the metric system is that it is based on powers of ten, which simplifies calculations and unit conversions.
3. Note that this base-10 structure allows scientists to easily convert between units by shifting decimal places, rather than using complex conversion factors.
4. Realize that the metric system's consistency and simplicity help reduce errors and improve communication among scientists internationally.
5. Conclude that the preference for SI units is due to their ease of use and universal acceptance, not because they are inherently more accurate or limited to certain regions.
