Key Concepts

SI Units

The International System of Units (SI) is a standardized system of measurement used globally in science and engineering. It consists of seven base units, including the meter for length, kilogram for mass, second for time, ampere for electric current, kelvin for temperature, mole for the amount of substance, and candela for luminous intensity. Derived units are formed from these base units to measure other quantities.

Temperature Measurement

Temperature is a measure of the average kinetic energy of the particles in a substance. In the SI system, temperature is measured in kelvins (K), where 0 K is absolute zero, the point at which molecular motion ceases. Other temperature scales, such as Celsius and Fahrenheit, can be converted to kelvins using specific formulas.

Derived Units

Derived units are combinations of the base SI units that are used to measure more complex quantities. For example, temperature in kelvins is a derived unit that can be expressed in terms of the base unit of thermodynamic temperature. Understanding how to express derived units in terms of fundamental units is essential for accurate scientific communication and calculations.
