unit:PlanckTime
  a qudt:Unit ;
  dcterms:description """
  In physics, the Planck time, denoted by $t_P$, is the unit of time in the system of natural units known as Planck units.
  It is the time required for light to travel, in a vacuum, a distance of 1 Planck length.
  The unit is named after Max Planck, who was the first to propose it.

  The formula for $\\textit{PlankTime}$ is:

  $$ \\\\ t_P \\equiv  \\sqrt{\\frac{\\hbar G}{c^5}} \\approx 5.39106(32) \\times 10^{-44} s$$

   where, $c$ is the speed of light in a vacuum, $\\hbar$ is the reduced Planck's constant
    (defined as $\\hbar = \\frac{h}{2 \\pi}$ and $G$ is the gravitational constant.
  The two digits between parentheses denote the standard error of the estimated value.
