Homonym: SI (Sine)
The International System of Units, commonly known as SI, is a standardized system used worldwide for measuring various quantities. It was established to provide a consistent framework for scientific and technical measurements, ensuring clarity and precision. The system includes seven base units, such as the meter for length and the kilogram for mass, from which other units can be derived.
SI is essential in fields like science, engineering, and commerce, as it facilitates communication and comparison of measurements across different regions and disciplines. By using SI, researchers and professionals can avoid confusion and errors that may arise from using different measurement systems.
