Why is it important for scientists and engineers to adopt a common system of measurement units such as the SI system?

• A. It restricts scientific research to only those countries that use the metric system.
• B. It eliminates the need for calibration of scientific instruments.
• C. It allows scientists to avoid using mathematical equations in their work.
• D. It ensures consistency and comparability of data across different experiments and countries.

Answer: (D)

Verified step by step guidance

1. Understand that scientific research is a global endeavor involving collaboration among scientists and engineers from different countries.
2. Recognize that using a common system of measurement units, such as the SI system, provides a standardized way to express and communicate measurements.
3. Realize that this standardization ensures that data from different experiments and sources can be directly compared and reproduced without confusion or conversion errors.
4. Note that without a common system, measurements could be misinterpreted or require complex conversions, leading to inconsistencies and mistakes.
5. Conclude that adopting the SI system promotes clarity, accuracy, and efficiency in scientific communication and engineering practices worldwide.
