The pages linked in the right-hand column contain lists of times that are of the same order of magnitude (power of ten). Rows in the table represent increasing powers of a thousand (3 orders of magnitude).

Note: Planck time, the shortest physically meaningful instant of time, is approximately 5.4 × 10−44 s.
