Final answer:
SI units, or International System of Units, are a standardized set of measurement units used in science and engineering. They offer advantages such as consistency, simplicity in calculations, and global uniformity.
Step-by-step explanation:
SI units, short for International System of Units, are a set of measurement units that are widely used in science and engineering. They provide a consistent and standardized way of expressing physical quantities. The advantages of SI units over traditional units are that they are based on fundamental physical constants and are easily convertible, making calculations and comparisons between different units much simpler. Additionally, SI units are used globally, which facilitates international communication and collaboration in scientific research.
