dcterms:description In physics, the Planck length, denoted \(\ell_P\), is a unit of length, equal to \(1.616199(97)×10^{-35}\) metres. It is a base unit in the system of Planck units. The Planck length can be defined from three fundamental physical constants: the speed of light in a vacuum, Planck's constant, and the gravitational constant.

qudt:latexDefinition \(\ell_P = \sqrt{\frac{ \hbar G}{c^3}} \approx 1.616199(97)) \times 10^{-35} m\), where \(c\) is the speed of light in a vacuum, \(\hbar\) is the reduced Planck's constant, and \(G\) is the gravitational constant. The two digits enclosed by parentheses are the estimated standard error associated with the reported numerical value.
