Tess Newman answered on 3 May 2012:
The smallest unit of distance that we can actually measure is an Angstrom – this is 10 million times smaller than a millimetre. There are even smaller units than this, a femtometer (also known as a fermi) is 100,000 times smaller, and is about the size of an atomic nucleus.
Of course, distance is not the only unit of measurement. It is thought that a unit known as Planck time is the smallest measurement of time that will be possible. It is roughly equal to 10^−43 seconds

I saw on this thing we did in class and it had planck length as smallest thing possible.
Tess commented on :
Yep – Planck length is even smaller than a femtometer, and is much smaller than even an electron – around 1.6×10^(−35) m
