Planck Time
Planck time, abbreviated as \(t_p\), is a fundamental unit in the system of Planck units. It is based on the speed of light, the energies needed to smash particles in the universe at a time equal to the Planck length and universal gravitational constant divided by the speed of light. It is a useful unit in theoretical physics.

\( t_p \) = Planck time (See Physics Constants) | \(sec\) | \(s\) |
\( G \) = gravitational constant | \(lbf-ft^2\;/\;lbm^2\) | \(N - m^2\;/\;kg^2\) |
\( h \) = Planck constant | \(lbf-ft\;/\;sec\) | \(J-s\) |
\( c \) = speed of light in vacuum | \(ft\;/\;sec\) | \(m\;/\;s\) |
