The smallest fraction of a second measured is of the order of 10-15 attoseconds
(10-15*10-18 seconds, or 10-15 quintillionths of a second).
According to the current understanding of the laws of physics, the smallest unit of time that can be measured is the Planck time which is approx 5.4*10-44 seconds.

A Centigram is the second smallest unit to measure mass
0 is the smallest non-negative fraction.
you order unit fraction like this by smallest to biggest or biggest to smallest
