It actually depends which Planck scale one is talking about.
What I call the Planck scale is the Planck energy scale which is huge, roughly equal to 10^19 GeV. The unification scale is thus roughly 10^16 GeV. And for the sake for the comparison, the scale probed at the LHC is roughly of 10^3-10^4 GeV. We still have a long way to go.
You can always convert the Planck mass into a Planck length by adjusting a prefactor depending on the Planck constant and the speed of light. And this one is small, as a length is the inverse of an energy in the unit system commonly used in particle physics.
I have edited my post to make this clearer. Thanks for reading it, and pointing it out!
