The Planck system, also known as natural units, is a system of measurement where the Planck units are used as fundamental units. It is named after the German physicist Max Planck, who was instrumental in the development of quantum theory. The Planck system is particularly useful in theoretical physics, as it simplifies many equations and reveals deep connections between different areas of physics.

The system is based on three fundamental physical constants: the speed of light in a vacuum (c), the gravitational constant (G), and the reduced Planck constant (ħ). From these, seven base units are derived: length, mass, time, electric charge, temperature, amount of substance, and luminous intensity. These units are known as Planck units.

The Planck length is the smallest measurable length in the Planck system, approximately 1.6 x 10^-35 meters. It is the scale at which quantum effects dominate over classical effects. The Planck mass is the smallest measurable mass, approximately 2.2 x 10^-8 kilograms. The Planck time is the smallest measurable time interval, approximately 5.4 x 10^-44 seconds.

The Planck system is not used in everyday life or practical applications, as it is too small for most purposes. However, it is a valuable tool for theoretical physicists, as it provides a consistent and dimensionally correct framework for exploring the fundamental nature of the universe. It is also used in the study of black holes, where the effects of quantum mechanics and general relativity are both significant.
