Planck time: 5.391 × e−44 seconds.
That's 0.000000000000000000000000
00000000000000000005391 second! If a proposed extension of the SI prefixes was to be used, then Planck time (tP) would be slightly larger than a rimto (10e-45) second.
(A nanosecond is only 0.000000001 second, which immediately makes it 10000000000000000000000
00000000000000 times larger than tP).
Although, technically there isn't one, because you can split the above into two halves. Scientists say that this is the smallest measurable amount of time. All smaller amounts are too small to matter.

Smallest Measurement Of Time

The smallest measurable time as claimed by scientists is 100 atto second or 1 x10 (-6) second.
The natural unit of time is the Planck's time. It is the time taken by a photon to cover a Planck's length.
It is 5.39121(140) x 10^(-44) second. and is smaller by a factor of 5.4 x10^ (-30) than the so far measured smallest time.
When we say, "at this instant" the time interval is zero.

In physics, the Planck time (tP), is the natural unit of time. Eponymously termed for Max Planck, it is considered to be the smallest possible interval of time. Named after paysicist Max Karl Ernst Ludwig Planck (April 23, 1858 – October 4, 1947)

For this you want to make every option have the same measurement. And fortunately since this is metric it's really easy. 1km = 1000 m 1m = 1m 1cm = 1/100m 1mm = 1/1000m So from here the measurements become: .50m 5m .0005m 500000m .01m And now all you need to do is compare the numbers.

There is limit to us being able to measure time. The standard unit of time in physical science is the second. Some events occur in a picosecond. Time can be infinitely short.

Planck time -- the time for light to travel the Planck length (the smallest possible length) ... about 10^-43 seconds.

There probably isn't one. After nanoseconds, we have picoseconds, then femto, then atto......... and it goes on. Also, infinitesimal digits can be placed in them, and you can't have a smallest measurement.
the smallest "measurement" I suppose, is a second.

A chemist told me that chemical reactions happen in femtoseconds (10^-15 s) at the molecular level. Daniel is probably right about Planck's time, it is probably linked to Heisenberg uncertainities inequations.

ONE UNIT of time may be sub-divided an INFINITE number of times.
The answer to your question therefore becomes:
"Infinitesimally small"
If by 'measurement' you meant UNIT of time then a standard Nano-second.
