Which term refers to the modernized metric system for measurements?

• A. International System of Units (SI)
• B. Metric units
• C. Liter
• D. Layout and Calculation

Answer: (A)

The modernized metric system is the International System of Units (SI). SI provides a standardized set of base units (like meter, kilogram, second) and prefixes (kilo-, milli-, etc.) so measurements are consistent worldwide. This is the system used in technical standards and engineering calculations, including sprinkler design, to ensure clarity and compatibility across disciplines. “Metric units” is a general term for units in the metric system, but the formal name for the modern system is SI. A liter is a unit of volume within SI, not the system itself, and “layout and calculation” isn’t related to measurement systems.
