Planck time is the fundamental time scale derived from physical constants and represents the smallest meaningful unit of time in quantum gravity.

Why convert Planck time to days?

Converting Planck time to days helps relate quantum-scale durations to familiar, everyday units used in science and timekeeping.

Is Planck time practical for everyday timekeeping?

No, Planck time is many orders of magnitude smaller than typical time units and is mostly relevant in theoretical physics.
