The International System of Units

The International System of Units (SI) is a standardized system for measuring quantities like length, mass, time, and temperature. It provides a common language for scientists, engineers, and everyday users worldwide, ensuring measurements are consistent and comparable. SI units include meters for length, kilograms for mass, seconds for time, and Kelvin for temperature. This system is based on universal constants, making it reliable and precise. It helps facilitate international trade, scientific research, and technological development by maintaining clear, universal measurement standards.
